A computing device of the manufacturing assembly (100), each process station or the management system (102) can provide an image recognition algorithm to identify features in the captured image. The image recognition means can be implemented by known technologies, so the details will not be repeated here.

The management system (102) receives the rewinding process data, the impregnation assembly process data, the aging process data, and the processing process data according to a work order assigned to the manufacturing assembly (100), and can generate a report based on at least these data The yield statistics are as mentioned above. The management system (102) can generate the yield statistics and more data (such as output statistics, work orders, order status, error analysis, and machine status) based on at least these data, and these results can be obtained through the terminal device (104) The display is presented to the user. In one embodiment, the management system (102) generates a process progress data based at least in part on the add-on coiling process data, the impregnation assembly process data, the aging process data, and the processing process data, which instructs each process station to respond to the work order.

In one embodiment, the management system (102) identifies one or more defective machines based at least in part on the addition and winding process data, the impregnation assembly process data, the aging process data, and the processing process data. The defective machine mentioned here means that a ratio of the yield rate and the defective rate of the finished product is regarded as an inefficient result. The management system (102) is based at least in part on the addition and winding process data, the impregnation assembly process data, the aging process data, and the processing process data. For events (such as whether there is a casing or not), the management system (102) provides statistics on these events and generates an event sequence data. The tenth figure shows a part of the display screen of the terminal device (104), which presents an example of event sequencing data, including the machine name (1001), event name (1002), number of occurrences (1003), and the affiliated process station (1004). , Such as assembly, aging) and the user graphical interface composed of the date of occurrence. As shown in the figure, there have been multiple incidents of machine name G38, which means that the proportion of defective products in the finished product of the machine may be relatively high, and inspection and adjustment of the machine is necessary.

In one embodiment, the management system (102) also receives all the machine statuses of the rewinding process station (207), the impregnation assembly process station (208), and/or the burn-in process station (209) and obtains all the machine statuses accordingly.

In this way, the user can quickly identify which process stations are available remotely without having to go to the machine to check one by one.

Figure 12 shows a flowchart of the capacitor manufacturing process management method of the present invention, including steps S1200 to S1206. In step S1200, at the processing station (202) of the plus-and-coiling process, a plurality of wires (such as the wire rod in the third figure) are respectively fixed to an anode foil and a cathode at a predetermined distance by a plurality of machines. Foil (as shown in the fourth figure), the anode foil and the cathode foil fixed with the wires and at least one electrolytic paper are wound into a plurality of elements (as shown in the fifth figure), and each is recorded according to a work order The machine detects an electrical characteristic and an appearance feature of each wire and each element, and the data of the winding process is generated. The recording is completed by the memory of the management system (102). The detection is completed by one or more second counting devices (207) as described above. The data of the add-on coiling process is statistics for a plurality of semi-finished products or products. The electrical characteristics and appearance characteristics of the wires and elements have been discussed above.

In step S1202, at the impregnation assembly process station (203), an electrolyte is injected into the elements by its multiple machines, and the elements injected with the electrolyte are packaged to form a plurality of capacitor products (such as the first Figure 6 and Figure 7), and record an impregnation assembly process data generated by each machine inspecting an appearance feature of each capacitor product according to the work order. The detection is completed by one or more third counting devices (208) as described above. The appearance characteristics of each capacitor product have been discussed above.

In step S1204, at the burn-in process station (204), a plurality of machines apply an burn-in voltage to the capacitor products, and according to the work order, each machine detects an electrical characteristic of each capacitor product and generates a burn-in process data. The detection is completed by one or more fourth counting devices (209) as described above. The electrical characteristics of each capacitor product have been discussed above. It should be understood that the aging voltage operation can be replaced with current operation or other operations, and is not limited to a specific operation. Products of the same work order should be subjected to the same aging operating voltage and the same aging time. The inspection here is implemented on the capacitor products after aging, rather than the products that have not been fully aging.

In step S1206, the process management system (102) generates a yield statistic based at least on the processing data of the add-on coiling process, the impregnation assembly process data, and the aging process data, which includes a ratio indicating that a work order is processed on the add-on coil. The proportion of defective products in the process station, the impregnation assembly process, and the aging process station can of course also generate a yield statistics representing the manufacturing assembly (100). Of course, in a feasible configuration, the management system (102) can also incorporate the aforementioned cutting process data or processing process data. It should be understood that there is a sequence relationship between the add-on coiling process station (202), the impregnation assembly process station (203), and the aging process station (204). Station (204) may not be operational yet. In this case, the management system (102) will only receive the roll-up process data. In other words, the management system (102) does not necessarily collect data from all stations at the same time. However, the management system (102) may collect data at regular intervals, or the management system (102) may open the reception of any data at any time. Therefore, the user graphical interface displayed by the terminal device (104) can be updated every time or continuously, so that the user can grasp the status of each process station.

The aforementioned data each represents a different meaning. For example, the data of the add-on winding process is about the yield of the wire itself and the element itself, which can be used to indicate the efficiency of the machines participating in the process at this stage. As another example, the impregnation assembly process data is about the yield of capacitor products (products with capacitive effects), which can be used to indicate the efficiency of the machines participating in the process at this stage. As another example, the aging process data is about the yield rate of the product itself that has been confirmed to have a capacitor effect, which can be used to indicate certain electrical defects of the capacitor product, and then predict which process station or machine needs to be improved. In addition, as mentioned, the process progress data and production quantity data are related to the number of products (including good and defective products) completed by each process station or each machine, which are used to indicate the accuracy or efficiency of a specific process station or machine to facilitate targeting Specific links to improve. The present invention is based at least on the establishment of these specific data, so that the user can accurately identify the defect of the capacitor manufacturing process and the location where it occurs, which helps to improve the yield of the capacitor.
