Description

Technical Field

[0001] This invention relates to the field of automatic transport control technology, and specifically to an automatic loading control method for battery products based on transport cycle matching. Background Technology

[0002] In the battery coating process, after being conveyed along the main conveyor path, the battery products are diverted into multiple branch conveyor paths and transported to the loading positions corresponding to different coating machines for loading operations. Due to the differences in conveying conditions and operating states of different branch conveyor paths, the arrival rhythm of battery products at each loading position exhibits dynamic changes. Some loading positions show continuous and rapid arrival, while others show a gradually increasing arrival interval.

[0003] During the transport process, the flow status of battery products in the buffer area changes synchronously. Specifically, the number of products entering and leaving the buffer area fluctuates dynamically with the transport rhythm, which may result in different buffer accumulation or release states corresponding to different loading positions of different coating machines in the same operating phase.

[0004] Existing loading control methods typically employ fixed loading waiting times or fixed loading sequences to control the loading process. These methods fail to dynamically adjust the loading rhythm in conjunction with changes in conveyor cycle time and buffer status. When the conveyor cycle time increases, fixed waiting times can easily lead to buffer backlog; when the conveyor cycle time decreases, fixed waiting times can easily cause loading response delays, thus affecting the overall continuity and coordination of loading. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes an automatic loading control method for battery products based on conveyor cycle matching. By introducing a combined judgment result based on the characteristics of conveyor cycle change and buffer state change during the process of conveying battery products to the corresponding loading positions of each coating machine, and dynamically correcting the loading waiting time of each loading position based on the combined judgment result, loading control of different loading positions under continuous conveying conditions can be achieved.

[0006] To achieve the above objectives, the present invention provides an automatic loading control method for battery products based on conveyor cycle matching, comprising the following steps:

[0007] The arrival time of the battery products at the detection points of each loading position in each branch conveying path at the end of the main conveying path is obtained, and the arrival time difference between adjacent battery products at the detection points is calculated as the conveying cycle time.

[0008] The change state of adjacent conveying cycles is determined based on the change difference between adjacent conveying cycles. The change state of adjacent conveying cycles includes a cycle speed-up state, a cycle speed-down state, and a cycle stability state.

[0009] The time interval corresponding to adjacent conveying cycles is used as the statistical time interval. Within the statistical time interval, the quantity change status of battery products in the buffer area is determined based on the difference between the number of battery products entering the buffer area and the number of battery products leaving the buffer area. The quantity change status includes an increase status, a decrease status, and a balance status.

[0010] Within the statistical time interval, the change status of each adjacent conveying cycle is matched one-to-one with the change status of the quantity of battery products in the buffer area. Based on the combined status results, the operating pressure status of each loading position is determined, and priority mapping is performed on each loading position based on the operating pressure status to determine the current target loading priority of each loading position.

[0011] The absolute value of the change in the adjacent conveying cycle time corresponding to each loading position within the statistical time interval is used as the basic correction amount. Based on the current target loading priority of each loading position and in combination with the basic correction amount, the loading waiting time correction amount is determined. Based on the loading waiting time correction amount of each loading position, the basic loading waiting time of each loading position is corrected to determine the corrected loading waiting time of each loading position.

[0012] When the battery product reaches the corresponding loading position, the timing is based on the corrected loading waiting time. When the timing reaches the corrected loading waiting time, the loading operation is performed.

[0013] The technical solution provided in this invention has at least the following technical effects or advantages: In response to the problems of dynamic fluctuations in conveying rhythm, changes in buffer area status, and difficulty in adaptive loading rhythm during the conveying of battery products to the corresponding loading positions of different coating machines at the end of a multi-branch conveying path, a combined judgment mechanism based on the characteristics of conveying rhythm change and the characteristics of buffer area quantity change is introduced, and the loading waiting time of each loading position is dynamically corrected based on the combined result, so as to achieve adaptive adjustment of loading rhythm of different loading positions under continuous conveying conditions. Specifically, by acquiring the arrival time of battery products at each detection point and calculating adjacent conveying cycles, a conveying rhythm change sequence is constructed to characterize the rhythm fluctuations of different loading positions during continuous conveying. The cycle change state is determined based on the difference in changes between adjacent conveying cycles, enabling the differentiation of conveying rhythm acceleration, deceleration, and stable states. A statistical window is constructed using the time intervals corresponding to adjacent conveying cycles, comparing the number of battery products entering and leaving the buffer area within this window to form a quantity change state, reflecting the accumulation or release trend of loading positions during conveying. The current target loading priority of each loading position is determined based on the combination of the cycle change state and the quantity change state, achieving differentiated distinction of operating states between different loading positions. Furthermore, the loading waiting time is corrected according to the current target loading priority, so that different loading positions in different operating states correspond to different waiting time adjustment strategies, thereby achieving dynamic adjustment of the loading rhythm.

[0014] Compared with existing technologies, this invention introduces both the conveying cycle time variation characteristics and the buffer area quantity variation characteristics during the conveying process, and determines the operating status of each loading position based on the combination of these two types of characteristics. This allows for unified judgment and differentiated distinction of the operating status between different loading positions. Furthermore, the loading waiting time is differentiated according to the corresponding relationship of the operating status, so that loading control no longer relies on fixed waiting parameters or a single conveying rhythm, but can be adjusted synchronously with changes in the conveying cycle time and buffer status. This improves the adaptability and stability of the loading process under continuous conveying conditions, reduces buffer backlog and loading waiting phenomena, improves loading efficiency, ensures the continuous material supply capacity of the corresponding loading position of the wrapping machine, and improves the operating efficiency of the production line.

[0017] This invention introduces a dynamic sensing mechanism for conveying rhythm and a linkage determination mechanism for buffer state.

Based on this combined state, it realizes loading priority division and adaptive correction of loading waiting time.

[0020] Example 1, as Figure 1 As shown, an automatic loading control method for battery products based on conveyor cycle matching includes the following steps:

[0021] S1. Obtain the arrival time of the battery products at the detection points of each loading position in each branch conveying path at the end of the main conveying path, and calculate the arrival time difference between adjacent battery products at the detection points as the conveying cycle time.

[0022] Specifically, after being output from the buffer area, the battery products enter the main conveyor path for continuous transport. At the end of the main conveyor path, they are branched into their respective branch conveyor paths according to the transport direction. Each branch conveyor path corresponds to a loading position, and detection points are set on the branch conveyor path corresponding to each loading position, marked as detection points P1, P2, ..., P... n Where n is the number of detection points, and the detection points are used to collect the arrival time of battery products through the corresponding branch conveying path. At detection point P i A battery product detection unit is installed at point P to record the battery product's passage through detection point P. i The time information is given by i, where i represents the detection point number, i={1,2,…,n}.

[0023] Before the conveying path is started, the time recording units at each detection point are calibrated to a unified time reference, ensuring that the time recordings at each detection point are based on this unified time reference. When the battery product passes detection point P along the conveying direction... i At that time, detection point P i Generate a trigger signal and record the corresponding transit time t. i (k) Where k represents the sequence number of the battery product passing through inspection point Pi, and t i (k) This indicates that the k-th battery product is detected at point P. i Arrival time.

[0024] For detection point P i The arrival time difference between two adjacent battery products is calculated according to the order in which they pass through, to obtain the arrival time P of the adjacent battery products at the detection point. i Time difference Δt i (k) , where Δt i (k) =t i (k+1) -t i (k) and Δt i (k) As a transport cycle, it is used to characterize the detection point P. i Characteristics of the battery product conveying cycle at the corresponding loading position.

[0025] S2. Determine the change state of adjacent conveying cycles based on the change difference between adjacent conveying cycles, wherein the change state of adjacent conveying cycles includes a cycle speed-up state, a cycle speed-down state, and a cycle stability state.

[0026] Furthermore, based on the difference in change between adjacent conveying cycles, the change state of adjacent conveying cycles is determined, including calculating the difference between adjacent conveying cycles to obtain the change amount of adjacent conveying cycles. When the change amount of adjacent conveying cycles is less than 0, the change state of adjacent conveying cycles is determined to be a cycle speed-up state; when the change amount of adjacent conveying cycles is greater than 0, the change state of adjacent conveying cycles is determined to be a cycle speed-down state; and when the change amount of adjacent conveying cycles is equal to 0, the change state of adjacent conveying cycles is determined to be a cycle stability state.

[0027] Specifically, for detection point P i The difference between two adjacent conveying cycles is calculated to obtain the change D between adjacent conveying cycles. i (k) =Δt i (k+1) -Δt i (k) And based on the change D of adjacent conveying cycles i (k) The positive or negative value is used to determine the change state of adjacent conveying cycles.

[0028] When D i (k) When <0, it indicates that the subsequent conveying cycle is shorter than the previous conveying cycle, and the battery product has reached the detection point P. i When the time interval decreases, the change in the adjacent conveying cycle is determined to be a cycle speed-up state;

[0029] When D i (k) When the value is greater than 0, it indicates that the subsequent conveying cycle is longer than the previous conveying cycle, and the battery product has reached the detection point P. i When the time interval increases, the change state of the adjacent conveying cycle is determined to be a cycle slowdown state;

[0030] When D i (k) When = 0, it indicates that the adjacent conveyor cycles are consistent and the battery products have arrived at the detection point P. i If the conveying cycle time remains unchanged, the change in the adjacent conveying cycle time is determined to be a stable cycle time state.

[0031] S3. The time interval corresponding to adjacent conveying cycles is taken as the statistical time interval, and the quantity change status of battery products in the buffer area is determined based on the difference between the number of battery products entering the buffer area and the number of battery products leaving the buffer area within the statistical time interval. The quantity change status includes an increase status, a decrease status, and a balance status.

[0032] Furthermore, within the statistical time interval, based on the difference between the number of battery products entering the cache area and the number of battery products leaving the cache area, the quantity change status of battery products in the cache area is determined, including: when the difference in quantity is greater than 0, the quantity change status of battery products in the cache area is determined to be an increasing state; when the difference in quantity is less than 0, the quantity change status of battery products in the cache area is determined to be a decreasing state; when the difference in quantity is equal to 0, the quantity change status of battery products in the cache area is determined to be a balanced state.

[0033] Specifically, based on the adjacent conveying cycle time Δt i (k) With Δt i (k+1) The corresponding time interval is the statistical time interval T. k Among them, due to the conveying cycle time Δt i (k) The corresponding battery product at time t i (k) With t i (k+1) The conveying process between them, the conveying cycle time Δt i (k+1) The corresponding battery product at time t i (k+1) With t i (k+2) The transmission process between them, therefore the statistical time interval T k Corresponding time t i (k) To t i (k+2) The time range between them.

[0034] In the statistical time interval T k Within the buffer area, the movement of battery products is continuously recorded, and the number of battery products entering the buffer area is recorded as Ni. (k) The number of battery products leaving the cache area is recorded as No. (k) Among them, the number of entries Ni (k) Indicates the statistical time interval T k The number of battery products entering the buffer area via the transport path, and the number leaving (No.) (k) Indicates the statistical time interval T k The number of battery products that flow out of the buffer area.

[0035] Based on the number of entries Ni (k) Number of departures No (k) The difference in quantity between them ΔN (k) The positive or negative value is used to determine the change in the quantity of battery products within the buffer area.

[0036] Where ΔN (k) =Ni (k) -No (k) ,

[0037] When ΔN (k) When >0, it indicates that within the statistical time interval T k If the number of battery products entering the buffer area is greater than the number leaving, the change in the number of battery products in the buffer area is determined to be an increasing state.

[0038] When ΔN (k) When <0, it indicates that within the statistical time interval T k If the number of battery products leaving the buffer area is greater than the number entering, the change in the number of battery products in the buffer area is determined to be a decreasing state.

[0039] When ΔN (k) When = 0, it indicates that within the statistical time interval T k If the number of battery products entering the buffer area is consistent with the number of battery products leaving the buffer area, the change in the number of battery products within the buffer area is determined to be in a balanced state.

[0040] S4. Within the statistical time interval, the change status of each adjacent conveying cycle is matched one-to-one with the change status of the quantity of battery products in the buffer area. Based on the combined status results, the operating pressure status of each loading position is determined, and priority mapping is performed on each loading position based on the operating pressure status to determine the current target loading priority of each loading position.

[0041] Furthermore, based on the combined state results, the operating pressure status of each loading position is determined, including:

[0042] When the adjacent conveyor cycle time changes to an accelerating state and the number of battery products in the buffer area increases, the operating pressure at the corresponding loading position is determined to be in an accelerating backlog state. When the adjacent conveyor cycle time changes to a stable state and the number of battery products in the buffer area increases, the operating pressure at the corresponding loading position is determined to be in a stable backlog state. When the adjacent conveyor cycle time changes to a decelerating state and the number of battery products in the buffer area increases, the operating pressure at the corresponding loading position is determined to be in a decelerating backlog state. When the adjacent conveyor cycle time changes to an accelerating state and the number of battery products in the buffer area is balanced, the operating pressure at the corresponding loading position is determined to be in an accelerating balanced state. When the adjacent conveyor cycle time changes to a stable state and the number of battery products in the buffer area increases... When the state is balanced, the operating pressure state of the corresponding loading position is determined to be a stable balanced state. When the adjacent conveyor cycle change state is a cycle deceleration state, and the change state of the number of battery products in the buffer area is a balanced state, the operating pressure state of the corresponding loading position is determined to be a deceleration balanced state. When the adjacent conveyor cycle change state is a cycle acceleration state, and the change state of the number of battery products in the buffer area is a decrease state, the operating pressure state of the corresponding loading position is determined to be an acceleration and pressure relief state. When the adjacent conveyor cycle change state is a cycle stabilization state, and the change state of the number of battery products in the buffer area is a decrease state, the operating pressure state of the corresponding loading position is determined to be a stable and pressure relief state. When the adjacent conveyor cycle change state is a cycle deceleration state, and the change state of the number of battery products in the buffer area is a decrease state, the operating pressure state of the corresponding loading position is determined to be a deceleration and pressure relief state.

[0043] Furthermore, based on the operational pressure status, priority mapping is performed on each loading location to determine the current target loading priority for each loading location, including:

[0044] When the operating pressure state of the loading location is in an accelerating backlog state, the current target loading priority of the corresponding loading location is determined as the highest priority; when the operating pressure state of the loading location is in a stable backlog state, a decelerating backlog state, or an accelerating equilibrium state, the current target loading priority of the corresponding loading location is determined as the second highest priority; when the operating pressure state of the loading location is in a stable equilibrium state or a decelerating equilibrium state, the current target loading priority of the corresponding loading location is determined as the medium priority; when the operating pressure state of the loading location is in an accelerating depressurization state, a stable depressurization state, or a decelerating depressurization state, the current target loading priority of the corresponding loading location is determined as the low priority.

[0045] Specifically, regarding detection point P iIn the same statistical time interval T k Within the system, adjacent conveyor cycle change states and quantity change states are matched one-to-one to form state combination pairs. Based on the results of the state combination pairs, the detection point P is then... i The operating pressure status at the corresponding loading location is determined.

[0046] When the adjacent conveyor cycle change state is the cycle speed increase state, and the quantity of battery products in the buffer area changes state is the increase state, it indicates that the battery products enter at an increased speed and the buffer area continues to accumulate, indicating that there is high operating pressure at the corresponding loading position. The operating pressure state of the loading position is determined to be the accelerated accumulation state.

[0047] When the adjacent conveyor cycle change state is a stable cycle state and the quantity change state of battery products in the buffer area is an increasing state, it indicates that the battery product entry speed remains stable but the buffer area continues to accumulate, indicating that there is a continuous accumulation trend at the corresponding loading position, and the operating pressure state of the loading position is determined to be a stable accumulation state.

[0048] When the adjacent conveyor cycle change state is a slowdown state and the quantity of battery products in the buffer area changes state is an increase state, it indicates that the battery product entry speed is reduced but the buffer area is still continuously accumulated, indicating that there is unreleased buffer pressure at the corresponding loading position, and the operating pressure state of the loading position is judged as a slowdown and accumulation state.

[0049] When the adjacent conveyor cycle change state is the cycle speed increase state, and the quantity change state of battery products in the buffer area is the equilibrium state, it indicates that the battery product entry speed increases and the buffer area maintains the balance of entry and exit. This means that the corresponding loading position maintains stable operation under high input state, and the operating pressure state of the loading position is determined to be the acceleration equilibrium state.

[0050] When the adjacent conveyor cycle change state is a stable cycle state and the quantity change state of battery products in the buffer area is a balanced state, it means that the battery product entry speed remains stable and the buffer area maintains a balance between entry and exit. This indicates that the corresponding loading position is in a stable operating state, and the operating pressure state of the loading position is determined to be a stable and balanced state.

[0051] When the adjacent conveyor cycle change state is a cycle slowdown state, and the change state of the number of battery products in the buffer area is a balanced state, it means that the battery product entry speed is reduced and the buffer area maintains an in-out balance. This indicates that the operating load of the corresponding loading position is gradually decreasing, and the operating pressure state of the loading position is determined to be a deceleration balance state.

[0052] When the adjacent conveyor cycle changes to an accelerated cycle state and the number of battery products in the buffer area decreases, it indicates that the battery products are entering at an increased speed but no backlog has formed in the buffer area. This means that the corresponding loading position maintains a high loading and releasing capacity, and the operating pressure state of the loading position is determined to be an accelerated pressure relief state.

[0053] When the adjacent conveyor cycle change state is a stable cycle state and the quantity change state of battery products in the buffer area is a decreasing state, it indicates that the battery product entry speed remains stable and no backlog forms in the buffer area. This means that the operating pressure at the corresponding loading position is gradually released, and the operating pressure state of the loading position is determined to be a stable pressure relief state.

[0054] When the adjacent conveyor cycle change state is a slowdown state, and the quantity of battery products in the buffer area changes to a decrease state, it indicates that the battery product entry speed is reduced and no backlog has formed in the buffer area. This means that the operating pressure at the corresponding loading position is continuously decreasing, and the operating pressure state of the loading position is determined to be a deceleration and pressure reduction state.

[0055] At the detection point P i After determining the operating pressure status of the corresponding loading location, a priority mapping process is performed on the loading location based on the operating pressure status to determine the current target loading priority of that loading location.

[0056] When the operating pressure at the loading location is in an accelerated backlog state, the current target loading priority at that loading location is set as the highest priority.

[0057] When the operating pressure status of the loading location is a stable backlog state, a decelerating backlog state, or an accelerating equilibrium state, the current target loading priority of the loading location is determined as the second highest priority.

[0058] When the operating pressure at the loading location is in a stable equilibrium state or a deceleration equilibrium state, the current target loading priority at the loading location is determined to be medium priority.

[0059] When the operating pressure status of the loading location is in an accelerating pressure relief state, a stable pressure relief state, or a decelerating pressure relief state, the current target loading priority of the loading location is determined to be low priority.

[0060] S5. Using the absolute value of the change in the adjacent conveying cycle time corresponding to each loading position within the statistical time interval as the basic correction amount, the loading waiting time correction amount is determined based on the current target loading priority of each loading position and in combination with the basic correction amount. Based on the loading waiting time correction amount of each loading position, the basic loading waiting time of each loading position is corrected to determine the corrected loading waiting time of each loading position.

[0061] Furthermore, based on the current target loading priority of each loading location and in conjunction with the basic correction amount, the loading waiting time correction amount is determined, including:

[0062] When the current target loading priority of each loading position is the highest priority or the lowest priority, the basic correction amount is used as the loading waiting time correction amount for each loading position; when the current target loading priority of each loading position is the second highest priority, half of the basic correction amount is used as the loading waiting time correction amount for each loading position; when the current target loading priority of each loading position is the medium priority, the loading waiting time correction amount for each loading position is set to 0.

[0063] Furthermore, based on the loading waiting time correction amount for each loading location, the basic loading waiting time for each loading location is corrected to determine the corrected loading waiting time for each loading location. Specifically, this includes...

[0064] When the current target loading priority of the loading location is the highest priority or the second highest priority, the base loading waiting time of the loading location is subtracted from the loading waiting time correction amount to obtain the corrected loading waiting time of the loading location; when the current target loading priority of the loading location is the low priority or the medium priority, the base loading waiting time of the loading location is added to the loading waiting time correction amount to obtain the corrected loading waiting time of the loading location.

[0065] Specifically, regarding detection point P i Obtain the statistical time interval T at the corresponding loading location. k The corresponding change in adjacent conveyor cycle time D i (k) and the change in adjacent conveying cycle time D i (k) The absolute value of the value is used as the base correction amount. Based on the current target loading priority of the loading location, the loading waiting time correction amount δ for that loading location is determined.

[0066] When the current target loading priority at the loading location is the highest priority or the lowest priority, the base correction amount is used as the loading waiting time correction amount δ for the loading location;

[0067] When the current target loading priority of the loading location is the second highest priority, half of the base correction amount is used as the loading waiting time correction amount δ for the loading location;

[0068] When the current target loading priority of the loading location is medium priority, the loading waiting time correction δ for the loading location is set to 0.

[0069] Based on the loading waiting time correction δ for that loading location, the base loading waiting time tc for that loading location is corrected to determine the corrected loading waiting time tw for that loading location. i (k) Wherein, the basic loading waiting time tc is the initial waiting time from when the battery product arrives at the corresponding loading position until the loading operation is performed, and tw i (k) This represents the corrected loading waiting time for the k-th battery product when it passes through the detection point Pi, corresponding to the loading position at detection point Pi.

[0070] When the current target loading priority of the loading location is the highest priority or the second highest priority, the base loading waiting time tc of the loading location is subtracted from the loading waiting time correction amount δ of the loading location to obtain the corrected loading waiting time tw of the loading location. i (k) ;

[0071] When the current target loading priority of the loading location is low or medium, the base loading waiting time tc of the loading location is added to the loading waiting time correction δ to obtain the corrected loading waiting time tw of the loading location. i (k) .

[0072] S6. When the battery product reaches the corresponding loading position, start timing based on the corrected loading waiting time. When the timing reaches the corrected loading waiting time, perform the loading operation.

[0073] Specifically, for the loading position corresponding to the detection point Pi, when the battery product arrives at the detection point Pi at the corresponding loading position, the arrival time ts of the battery product is recorded. i (k) and the arrival time ts i (k) As the start time of loading timing, where ts i (k) This represents the time information when the k-th battery product arrives at the detection point Pi.

[0074] The arrival time ts of the battery product i (k) As the start time of the loading wait, the adjusted loading wait time tw i (k) Then, the loading execution signal at the corresponding loading position is triggered, and the loading operation is executed at the corresponding loading position.

[0075] For detection points P1, P2, ..., Pn corresponding to different loading positions, independent loading control is performed based on the corrected loading waiting time for the corresponding loading position.
