Therefore, different quality grades in the plurality of battery diaphragm sub-rolls can be subjected to station division management, so that unqualified products can be uniformly processed, and the risk of entering a market at the subsequent time is reduced.

Optionally, the quality detection system 100 in this embodiment is disposed on one side of the battery separator sub-roll, and is configured to scan the battery separator sub-roll at each station to detect and determine whether the battery separator sub-roll is qualified. Specifically, the quality detection system 100 is a CCD system commonly used by those skilled in the art, and has an optical system, an image sensor, and an image processing module, so as to achieve the effects of scanning, photographing and recording products on a plurality of stations, and according to the setting conditions of the operator, sequentially photographing the battery diaphragm sub-rolls on each station at intervals in the process of gradually moving the battery diaphragm sub-rolls to the winding position, and detecting the defects of the corresponding battery diaphragm sub-rolls on each station. Further, a preset standard is preset on the quality detection system 100, and the grade of the separator sub-coil of the battery can be determined by comparing the defect with the preset standard.

Illustratively, the battery separator sub-rolls may be classified into two grades, namely, acceptable and unacceptable grades, and in other embodiments, may be classified into a plurality of grades such as A, B, C according to specific needs, so as to refine and manage the quality of the finished product and improve the yield thereof.

Optionally, the indicator light 10 comprises a first spotlight 11 and a second spotlight 12. In this embodiment, the indicator lamps 10 are arranged in one-to-one correspondence with the stations, and can emit laser, and are arranged towards the battery diaphragm sub-rolls on the stations, so that the laser can be irradiated on the battery diaphragm sub-rolls, and the operator can observe the laser conveniently. As shown in fig. 1 and 2, optionally, a plurality of indicator lamps 10 are disposed on the support 30 at intervals, and in this embodiment, the angle of the indicator lamps 10 is adjustable and replaceable, so as to facilitate subsequent maintenance. Specifically, the number of indicator lights 10 corresponds to the number of stations, which is greater than or equal to the number of slit battery separator sub-rolls. In the specific use process, on the station without the battery diaphragm sub-coil, the indicator lamp 10 is turned off and does not emit laser any more, so that the operator is prompted that no product exists on the station without laser irradiation, the accurate identification of the station where the product is located by the operator is realized, the observation range is reduced, and the attention to the product is improved.

Further, each indicator light 10 has at least a first state, a second state and a third state. Specifically, when the battery separator sub-roll is a defective product, the indicator lamp 10 on the station corresponding to the defective product is in the first state; when the battery separator sub-roll is a qualified product, the indicator lamp 10 corresponding to the qualified product is in the third state.

Further, in this embodiment, the identifying device 20 is configured to scan the grade label 60, detect and judge information on the grade label 60, compare the information with the entered information of the battery separator sub-roll, and when abnormality occurs due to mismatch between the information on the grade label 60 and the system data, the indicator lamp 10 corresponding to the attached battery separator sub-roll is in the second state, so as to prompt the operator. For example, the information anomaly may include a deviation between the information content of the grade label 60 and the recorded information content, that is, a deviation between the station where the information of the grade label 60 is read and the station where the information is pasted, that is, a situation where the operator pastes the grade label 60 of the defective product in the battery separator sub-roll to the qualified station, and the quality label 60 is pasted in a similar way, and the identification error is caused. In this way, in the second state of the indicator lamp 10, the operator can conveniently identify the error of the content of the grade label 60 or the error of the pasting position of the grade label, so that the problem of mixing and placing the subsequent qualified products and unqualified products is avoided, and the second error prevention of unqualified product identification is realized.

Alternatively, the first shot 11 in the third state may also illuminate a pattern of "v" or "O" on the battery separator sub-roll, and the second shot 12 in the first state may also illuminate a pattern of "x" on the battery separator sub-roll to visually observe the station positions of the acceptable and unacceptable articles. Further, the first spotlight 11 and the second spotlight 12 in the second state are both set to be normally lighted or flash, and the irradiation mode of the first spotlight 11 is different from that of the second spotlight 12 in the first state and the first spotlight 11 in the third state, so as to distinguish the first state, the second state and the third state. For example, in the second state, the first spot lamp 11 may flash and the second spot lamp 12 may be turned on for warning, or the first spot lamp 11 and the second spot lamp 12 may flash alternately, so that the operator can recognize that the content on the grade label 60 has deviation or has a paste industrial error when the identifying device 20 identifies the content, and the grade label 60 is pasted with errors and corrected in time, thereby avoiding unqualified products entering the market and reducing production loss. In other embodiments, the first state, the second state and the third state may be clearly distinguished, and the colors of the first spotlight 11 and the second spotlight 12 and the power of the emitted laser may be set according to practical use, so that the operator can observe the light conveniently, which is not limited herein.

Specifically, the PLC controller 40 can control the indicator lamp 10 to switch between the third state and the first state according to the feedback result of the quality detection system 100, and at the same time, the PLC controller 40 can also control the indicator lamp 10 to switch from the third state or the first state to the second state according to the feedback result of the recognition device 20 when the attached station recognition data and the system data do not match. Illustratively, the identification device 20 in the present embodiment has functions of functional image collection, two-dimensional code identification, and data matching. Specifically, the identification device 20 is configured as an AI camera, and is capable of identifying the quality level identified by the quality detection system 100, the order of the level labels 60, and the color or state of the indicator light 10, so as to facilitate accurate comparison of the information of the level labels 60.

Optionally, the MES system 50 has a visual screen on which the condition of each station can be observed, and after the quality detection system 100 determines that an acceptable or unacceptable product is detected, the corresponding station on the visual screen synchronously displays green or red. Specifically, displaying green indicates that the product at the station is a good product, and displaying red indicates that the product at the station is a bad product. Further, the MES system 50 drives the printing device to print the grade label 60 of the corresponding station information for subsequent use by the operator for manual labeling. Optionally, the level tag 60 is provided with a two-dimensional code, and the identification device 20 can scan and identify the two-dimensional code, so as to facilitate comparison and analysis with system data.
