[0038] Example 1: This embodiment discloses a feeding cooperative control method, which acts on multiple transport lines with multiple process equipment in the battery cell production scenario. Specifically, relatively independent (several) process equipment are combined, and when problems occur, the entire line can respond immediately to dynamically adjust the production of the entire line, ensuring that problems with some process equipment will not affect the shutdown of the entire line. After the problem is solved, the restart will not increase the operating load due to the accumulation of materials at the front end, thereby improving the stability of the production of the process equipment. For details, refer to Figure 1 ,include:

[0039] S1: Receive feed signals, monitor status signals of various process equipment, and control feed and transport operations;

[0040] In this embodiment, the status signal of each process equipment can be monitored by sensors or external monitoring process equipment, or each process equipment can trigger the status signal autonomously, including normal signals (working) and abnormal signals (faults). It can be understood that when each process equipment is in normal working state, it can be operated with the preset feeding frequency (amount) and transportation (amount / frequency), that is, each process equipment is executed with the preset program to realize the autonomous transportation of materials (cells / silicon wafers).

[0041] S2: When a process equipment feeds back an abnormal signal, the position L of the process equipment is determined ij, where i is the transport line number and j is the process equipment number;

[0042] In this embodiment, if the process equipment feeds back an abnormal signal, the process equipment may fail, and thus the position of the process equipment needs to be confirmed to dynamically adjust the operating status of other process equipment on the corresponding entire line.

[0043] S3: dynamically adjusting the feeding frequency, material distribution on each process equipment and transportation line according to the position of the process equipment;

[0044] The dynamic adjustment includes but is not limited to the following: controlling the transportation line where the process equipment that feedbacks the abnormal signal is located to suspend the distribution of feed; and / or, other process equipment located in front of the process equipment that feedbacks the abnormal signal waits; and / or, other process equipment located behind the process equipment that feedbacks the abnormal signal waits after transferring materials.

[0045] Specifically, as an example, the dynamic adjustment includes controlling the i-th transport line to stop feeding, and at the same time controlling the i-th m-th process equipment to wait, where m=1, 2,...j-1, and controlling the i-th n-th process equipment to transfer materials and then wait, where m=n+1,...k, k is the total number of process equipment on the i-th transport line.

[0046] Based on the above, in this embodiment, when any process equipment fails / abnormally, the feed of the transportation line and the operation of the process equipment before and after the process equipment are adjusted. Specifically, for other process equipment located in front of the process equipment, it is necessary to wait temporarily, and for other process equipment located behind the process equipment, it is necessary to maintain the original working state and suspend work after all materials are transferred.

[0047] For example only, see Figure 2 , materials are set to have two transport lines during operation, each of which needs to pass through three (process) equipment (performing three different process operations). When equipment abnormality (downtime) occurs on line 1_1, 2_1, 3_1, the front end of the downtime process equipment will stop feeding, and the back end will not be affected and operate normally. At the same time, the handling equipment (feeding equipment) 1 will only transport materials to 1_2, and reduce the frequency of material transportation, and reduce the production speed of equipment 1 to achieve production balance; on the contrary, if line 1_2, 2_2, 3_2 finds abnormality (downtime), then the handling equipment 1 will only transport materials to 1_1, and reduce the frequency of transportation, and reduce the production speed of equipment 1. If 1_1 and 1_2 are downtime at the same time, the production of feeding equipment 1 will be stopped to ensure that materials will not accumulate.

[0048] Based on the above, it can be understood that in the present embodiment, each transport line and process equipment are integrated and controlled. For each process equipment, when an abnormality is detected, the output of the feeding equipment is controlled to dynamically adjust the working status of each transport line, that is, to increase the status linkage between the transport line and the process equipment, and reduce the situation where materials are accumulated due to abnormalities in the process equipment.

[0049] In this embodiment, the linkage with the feeding equipment, specifically when a transport line is controlled to suspend feeding, the feeding frequency of the feeding equipment is updated with a preset reduction. As mentioned above, the autonomous and dynamic linkage reduces the feeding of the feeding equipment to the transmission line to reduce the accumulation of materials after the process equipment is abnormal.

[0050] In this embodiment, for each process equipment in each transport line, material is transported by a material transfer mechanism; further, when the material transfer mechanism feeds back an abnormal signal, the position of the process equipment on both sides of the material transfer mechanism is determined for dynamic adjustment. In an optional embodiment, a monitoring sensor or other process equipment (used to monitor whether there is material accumulation on each process equipment) can also be set on each process equipment. When any process equipment feeds back that there is material accumulation, and the process equipment itself does not feed back an abnormal signal (i.e., no fault occurs), it is determined that the material transfer mechanism is faulty, and dynamic adjustment can be performed according to the position of the process equipment.

[0051] Specifically, the above-mentioned dynamic adjustment may be similar to the processing of the abnormality of a certain process equipment mentioned above, that is, the process equipment in front of it is temporarily suspended, while the subsequent process equipment operates normally; it may also be a customized processing, such as controlling the process equipment on both sides of the abnormal material transfer mechanism to skip. Specifically, the material transfer mechanisms located before and after the abnormal material transfer mechanism are set to work (update their working parameters / moving range), and directly move the material from the previous material transfer mechanism to the subsequent process equipment, thereby reducing the impact of the material transfer mechanism failure on the entire line operation.

[0052] In a preferred embodiment, for process equipment that feeds back abnormal signals, it indicates that the process equipment has a fault and requires operator assistance for maintenance. In this embodiment, the transmission of the entire line can be restored autonomously after the fault is eliminated. Specifically, the process equipment that feeds back abnormal signals is monitored in real time, and the i-th transport line is restarted autonomously when the abnormal signal is eliminated. When the abnormal signal is eliminated, it is confirmed that the fault has been eliminated. At this time, the feeding equipment will be reset to the normal working state to distribute and transport materials without manual operation, effectively improving work efficiency.

[0053] In a preferred embodiment, the abnormality of some process equipment may be resolved by resetting / restarting, so the control method can also realize autonomous maintenance of process equipment. Specifically, before controlling the transport line to stop feeding, an instruction is sent to control the process equipment that feedbacks the abnormal signal to restart a preset number of times, and the status signal is updated in real time. When the number of times the abnormal signal is received exceeds the threshold, the transport line is controlled to stop feeding. If it is still abnormal after multiple restarts, the operator is required to perform maintenance. Multiple reset controls can also reduce the situation where abnormal feedback signals are caused by misjudgment of process equipment, affecting the feeding of the entire line, thereby further improving work efficiency.

[0054] Based on the above, the control method provided in this embodiment integrates the control of multiple transport lines and process equipment on each transport line, and intelligently links the entire line in the battery cell preparation scenario to achieve dynamic load adjustment. When each process equipment operates normally, it autonomously executes material feeding, distribution to each transport line and material transportation. When any process equipment operates abnormally, it autonomously and dynamically adjusts, specifically controlling the feeding equipment to adjust the feeding frequency, controlling the prior (before the abnormal equipment) process equipment to wait, and the subsequent process equipment to operate normally, etc., thereby reducing the accumulation of materials at abnormal process equipment and affecting the process of the entire line.

[0055] It is understandable that the above control method may also add preset existing available steps to deal with specific fault conditions.

[0056] It is also supplemented that each step of the control method of the above embodiment can be implemented by software, hardware (the control module of the second embodiment described below) or a combination thereof. Specifically, the above method can be implemented by a computer process device, which at least includes but is not limited to: a memory, a processor, and multiple storage media on which programs are stored. When the programs are executed by the processor, corresponding functions are implemented to implement the method of the above embodiment.

[0057] Embodiment 2: This embodiment provides a feeding cooperative control system, see Figure 3 , including multiple transportation lines, each of which has several process equipment; feeding equipment, used to provide materials to each transportation line; material moving mechanism, used to transport materials between various process equipment; control module, used to receive feeding signals, monitor the status signals of various process equipment, and control the execution of feeding and transportation operations; when a certain process equipment feeds back an abnormal signal, the position of the process equipment is determined, and the feeding frequency, the material distribution of each process equipment and the transportation line are dynamically adjusted according to the position of the process equipment.

[0058] The material collaborative control system of this embodiment executes the control method described in the above-mentioned embodiment 1, and controls each process equipment, feeding equipment, and material transfer mechanism on each transportation line in a linkage manner through a control module. When an abnormality occurs, the control module can adjust the material distribution of the entire line, thereby reducing the accumulation of materials in the event of an abnormality, improving the safety of the use process, and improving work efficiency.

[0059] Specifically, the linkage control of the feeding equipment is based on the control module updating the working parameters of the feeding equipment after detecting the abnormal signal. Specifically, as described in the first embodiment, the output of the feeding equipment can be reduced according to the feeding status of each transport line.

[0060] It should be noted that the above-mentioned process equipment is the process equipment used in the battery cell preparation process. As examples, they include but are not limited to texturing process equipment, diffusion furnaces, anti-reflection film coating process equipment, screen printing process equipment, etc. It can be understood that the above-mentioned process equipment is the process equipment corresponding to each preparation process in the actual scenario, wherein each process equipment may also include one or more sub-process equipment, and the materials are transferred between the sub-process equipment through a conveyor belt, without the need for a material transfer mechanism. When any of the sub-process equipment fails, the process equipment will feedback an abnormal signal.

[0061] It can be understood that in addition to the above-mentioned process equipment, the feeding collaborative control system can also be arranged with sensors and other monitoring process equipment, and can also be connected to other devices / process equipment / modules available in other battery cell preparation scenarios to adapt to different application scenarios.

[0062] It should be noted that the embodiments of the present invention have better practicability and do not impose any form of limitation on the present invention. Any technician familiar with the field may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, any modification or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
