Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular, to a start-stop method for a double steel belt thinning and laminating machine. Background Art

[0002] The double steel belt thinning and laminating machine is a key equipment used in the dry electrode preparation process. It is a process that compresses powder materials into a belt through double steel belts, then thins and recompresses, and finally laminates. Currently, the operations of various types of machines are relatively similar. However, in the case of increasing functional requirements, there is an urgent need to integrate operation functions. At the same time, due to the material problem of the powder materials, the material after forming a film is relatively brittle and has a low bearing strength of destructive force, and the belt is prone to breakage during the start-up acceleration or stop deceleration process.

[0003] Therefore, there is an urgent need to develop a new start-stop method for the double steel belt thinning and laminating machine to overcome the problem of belt breakage of the double steel belt thinning and laminating machine. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a start-stop method for a double steel belt thinning and laminating machine that overcomes the above problems or at least partially solves the above problems.

Without conflict, the technical features in the embodiments of the present invention and the embodiments can be combined with each other.

[0024] Figure 1 is a schematic flow chart of a method for starting and stopping a double steel belt thinning composite machine provided by an embodiment of the present invention. As Figure 1 shown, the method for starting and stopping the double steel belt thinning composite machine includes the following steps: S1. After the machine is powered on, the initial state is the manual mode. In the manual mode, start the roller heating and start the heating rods on the outer sides of the double steel belts. S2. Start the pressure application and start the gap adjustment to keep the roll gap within the range of the set process value. S3. Reset the machine and check the equipment status of the machine. After the equipment status is checked and found to be correct, start all the functional actions of pressure application, gap adjustment, and action return to the original at the same time. S4. Confirm whether the machine alarms. If there is an alarm, control the machine to stop and execute step S3. If there is no alarm, execute step S5. S5. Wait for the pressure application and gap adjustment to be completed, and for each action to return to the original (completion judgment: compare the set value with the current value, and the in-place signal is the same as the action target). If there is no alarm and after all actions return to the original, and the reset start exceeds a predetermined time (for example, 5 s) at the same time, the reset is completed. S6. Switch the machine to the automatic mode. S7. Confirm whether the tape is broken. If the tape is broken, execute step S8 to lead the tape. If the tape is not broken, execute step S9 to select start or switch to manual mode; S8. Enter the tape leading state. After leading the tape again based on the tape break position and completing it, enter the start state, prepare to start all drive rollers to rotate, and at the same time control the start of pressure application, the start of gap adjustment and having been adjusted, the start of temperature adjustment and having been adjusted, and the start of all cylinder actions, and execute step S10; S9. Enter the start state, prepare to start all drive rollers to rotate, and at the same time control the start of pressure application and having been adjusted, the start of gap adjustment and having been adjusted, the start of temperature adjustment, and the start of all cylinder actions, and execute step S10; S10. Judge whether the conditions for the line body to rotate are met. If the conditions are met and there is no alarm, execute step S11a or S11b. If the conditions are not met and there is an alarm, stop and return to step S7; S11a. Start running the tape at low speed. After the tape leading is in place, manually select stop, alarm stop, or select start. If start is selected, execute step S12; S11b. Start running the tape at low speed and execute step S12; S12. After the drive rollers rotate, start the tension swing roller adjustment, and at the same time monitor the position of the tension servo motor swing roller. When the swing roller reaches the positive and negative limit positions, by increasing or decreasing the speed of the swing roller, keep the swing roller at the middle position. After all line segment tension adjustments are completed, start to accelerate in stages to perform high-speed tape running.

[0025] In the embodiment of the present invention, the operation interface of the machine table is as Figure 2 shown in the reference. The operation interface includes a display interface and five functional operation buttons, namely reset, manual / automatic switch, start, tape leading, and stop. Each functional button is provided with an indicator light, and the on or off of the indicator light is used to indicate whether the corresponding function action is enabled; the display interface is used to display corresponding data or text prompts.

[0026] Of course, in the embodiment of the present invention, the machine table can be configured with a buzzer for alarming, and the buzzer will generate a buzzer alarm when triggering the three function actions of start, tape leading, and reset.

[0027] After the machine table is powered on, it is in a silent state. Generally, there is no danger and no alarm is required. At this time, the machine table is in the process of waiting to run. Since the heating time is relatively long, in step S1 of the embodiment of the present invention, the method includes: after the machine table is powered on, if the machine table is in a silent state without alarm, during the process of the machine table waiting to run, pre-heating or pre-pressure application is performed before starting, and the pre-heating and pre-pressure application actions can be performed simultaneously or separately.

[0028] In step S2 of the embodiment of the present invention, the set process value for keeping the roll gap within the range of the set process value includes the action being executed to the set pressure value and / or gap value. The pressure value and the gap value can be set according to actual application requirements, and the embodiments of the present invention have no limitation on this.

[0029] In step S3 of the embodiment of the present invention, the method includes: when the machine is powered on for the first time, reset the machine. The system of the machine determines whether to switch to the automatic mode according to the detection result of signal acquisition. If there is an alarm in the system detection result, stop the reset. After solving the problem shown by the alarm, reset the machine again, and repeat this process until the reset is completed. When the operator intends to run the machine, in the case of the machine being powered on for the first time, it is necessary to first reset the machine. During this process, the system will judge whether it can run automatically according to signal acquisition and data detection. There is at least 5S of system monitoring and judgment time. If there is an alarm detected by the system, the reset cannot be completed and the reset is stopped.

[0030] In step S5 of the embodiment of the present invention, after the pressurization and gap adjustment are completed, control the functional components corresponding to the pressurization and gap adjustment to perform the action of returning to the original state (i.e., reset). If there is no alarm, it can be considered that the reset is completed; during the reset process, the functional components corresponding to the pressurization and gap adjustment cannot stop. After the reset is completed, the gap adjustment stops.

[0031] It should be noted that in the embodiment of the present invention, since both the pressurization and the gap adjustment need to be executed in the manual mode, correspondingly, the reset function and the automatic mode are not executed. Then, after the reset is completed, step S6 can be executed to switch the machine to the automatic mode.

[0032] In step S7 of the embodiment of the present invention, it is necessary to confirm whether the prepared electrode is broken. According to the confirmation result of whether it is broken, select to execute the subsequent steps, such as entering the tape guiding state or the starting state, or you can also select to switch the state of the machine. For example, switch the automatic mode at this time to the manual mode.

[0033] In step S8 of the embodiment of the present invention, the method includes: checking whether there are interference conditions during the system operation. When there is no interference during the system operation, perform the initial slow tape running. After the tape guiding is completed, the tape running does not stop and directly enters the starting state and executes the starting acceleration; the speed and gear settings of the tape running can be determined according to actual application requirements, and the embodiments of the present invention have no limitation on this.

[0034] After switching to the automatic mode, you can choose to lead the tape or start. When choosing to lead the tape, the system detects the running interference conditions. For example, if the pressing cylinder conflicts with the tape leading, it will cause interference and they cannot be carried out simultaneously. If there is no interference, the process of slow tape running in the initial gear will be carried out. After the tape leading is completed, it can be directly started and accelerated without stopping. When choosing to start, it is impossible to directly switch to the tape leading function without stopping. During the starting process, if you want to lead the tape manually, you need to stop before switching to the tape leading function.

[0035] In step S10 of the embodiment of the present invention, determining whether the conditions for the rotation of the wire body are met includes detecting whether there are interference conditions, etc. Referring to the foregoing content, if the conditions for the rotation of the wire body are met, the subsequent steps are executed.

[0036] It should be noted that during the execution of the three functional actions of reset, tape leading, and start in the embodiment of the present invention, the system will automatically detect the signal abnormality of the machine. When there is a signal abnormality, it will immediately alarm and stop. During these three processes, it is also possible to manually select to stop at any time. When the machine stops, clicking the alarm clear can clear all alarms without muting the buzzer sound.

[0037] During the operation process, in the embodiment of the present invention, different functions are marked by the number of bits of binary 0 and 1, which are used as the key conditions for operation interlock. In the embodiment of the present invention, the function flag bits of each functional action are defined as b(x…n), where x represents the number of machines, and n represents the current functional action, and n≤7.

[0038] Specifically, the functional actions correspond one-to-one with the values of n, that is, the function flag bits respectively correspond to seven functional actions, including: b(1…1) represents manual; b(1…2) represents automatic; b(1…3) represents during the reset process; b(1…4) represents stop; b(1…5) represents reset completed; b(1…6) represents during the running start process; b(1…7) represents during the tape leading running process.

[0039] On the other hand, in the embodiment of the present invention, a bit flag bit is added after the function flag bit to obtain a status flag bit b(x…n)=y, where y is 0 or 1. When y is 0, it represents that the corresponding functional action stops, and when y is 1, it represents that the corresponding functional action starts; and the status flag bits corresponding to the seven functional actions are combined to obtain a status parameter representing the operation state of the machine, and a text prompt after executing the corresponding functional action is generated.

[0040] According to the principle of the startup step sequence, there are 12 operating states. In the embodiments of the present invention, the state flag bits corresponding to the seven functional actions are combined to obtain state parameters representing the operating state of the machine tool, specifically including: When the state flag bit combination is b(1…1)=1, b(1…2)=0, b(1…3)=0, b(1…4)=0, b(1…5)=0, b(1…6)=0, b(1…7)=0, the first state parameter is obtained, representing the state of just being powered on, in the manual state, and not yet completed the reset; When the state flag bit combination is b(1…1)=1, b(1…2)=0, b(1…3)=1, b(1…4)=0, b(1…5)=0, b(1…6)=0, b(1…7)=0, the second state parameter is obtained, representing the state of being in the reset process in the manual state; When the state flag bit combination is b(1…1)=1, b(1…2)=0, b(1…3)=0, b(1…4)=1, b(1…5)=0, b(1…6)=0, b(1…7)=0, the third state parameter is obtained, representing the state of being manually stopped during the reset process in the manual state; When the state flag bit combination is b(1…1)=1, b(1…2)=0, b(1…3)=0, b(1…4)=1, b(1…5)=0, b(1…6)=0, b(1…7)=0, the fourth state parameter is obtained, representing the state of being stopped by system alarm during the reset process in the manual state; When the state flag bit combination is b(1…1)=1, b(1…2)=0, b(1…3)=0, b(1…4)=0, b(1…5)=1, b(1…6)=0, b(1…7)=0, the fifth state parameter is obtained, representing the state of the reset being completed in the manual state; When the state flag bit combination is b(1…1)=0, b(1…2)=1, b(1…3)=0, b(1…4)=0, b(1…5)=1, b(1…6)=0, b(1…7)=0, the sixth state parameter is obtained, representing the state of not being started and tape guiding in the automatic state; When the state flag bit combination is b(1…1)=0, b(1…2)=1, b(1…3)=0, b(1…4)=0, b(1…5)=1, b(1…6)=1, b(1…7)=0, the seventh state parameter is obtained, representing the state of starting and running in the automatic state; When the state flag bit combination is b(1…1)=0, b(1…2)=1, b(1…3)=0, b(1…4)=1, b(1…5)=1, b(1…6)=0, b(1…7)=0, the eighth state parameter is obtained, representing the state of being manually stopped during the startup process in the automatic state; When the status flag bit combination is b(1…1)=0, b(1…2)=1, b(1…3)=0, b(1…4)=1, b(1…5)=1, b(1…6)=0, b(1…7)=0, the ninth status parameter is obtained, which represents the state of the system alarm stop during the startup process in the automatic state; When the status flag bit combination is b(1…1)=0, b(1…2)=1, b(1…3)=0, b(1…4)=0, b(1…5)=1, b(1…6)=0, b(1…7)=1, the tenth status parameter is obtained, which represents the state of tape guiding in the automatic state; When the status flag bit combination is b(1…1)=0, b(1…2)=1, b(1…3)=0, b(1…4)=1, b(1…5)=1, b(1…6)=0, b(1…7)=0, the eleventh status parameter is obtained, which represents the state of manual stop during the tape guiding process in the automatic state; When the status flag bit combination is b(1…1)=0, b(1…2)=1, b(1…3)=0, b(1…4)=1, b(1…5)=1, b(1…6)=0, b(1…7)=0, the twelfth status parameter is obtained, which represents the state of system alarm stop during the tape guiding process in the automatic state.

[0041] In the embodiments of the present invention, the text state of the corresponding operation can be saved by defining a text number with the name of "TextNumber" for INT data. Among them, in the above 12 machine operation states, the operator can select the above 7 function actions at any time. Then, 42 text prompts can be generated according to the permutation and combination. One text number can correspond to one text prompt. In the embodiments of the present invention, the numbers and texts are pre-edited correspondingly. Finally, different numbers correspond to different text descriptions, and the descriptions of the text prompts are prompted according to the above process.

[0042] Then, according to the operation process, the limit value range of the text number in each operation state is divided as follows: TextNumber>=0 and TextNumber<=4, for state 1; TextNumber>=5 and TextNumber<=8, for state 2; TextNumber>=9 and TextNumber<=12, for state 3; TextNumber>=13 and TextNumber<=17, for state 4; TextNumber>=18 and TextNumber<=21, for state 5; TextNumber >= 22 and TextNumber <= 24, for status 6; TextNumber >= 25 and TextNumber <= 28, for status 7; TextNumber >= 29 and TextNumber <= 30, for status 8; TextNumber >= 31 and TextNumber <= 33, for status 9; TextNumber >= 34 and TextNumber <= 36, for status 10; TextNumber >= 37 and TextNumber <= 38, for status 11; TextNumber >= 39 and TextNumber <= 41 is for status 12; The 12 operation states corresponding to the text number correspond to the aforementioned twelve state parameters, and they can be matched and set according to actual requirements. Among them, for the division of the limit range of the text number, it is determined according to the process. For example, for status 1, in addition to the initial state operation prompt of TextNumber = 0, there are also 4 function buttons whose functions cannot be triggered. If these 4 function buttons are pressed forcefully, it is necessary to display a text prompt indicating that the function button has been pressed and why there is no effect. Therefore, 5 groups of prompts are required, that is, TextNumber is 0, 1, 2, 3, and 4 respectively. For example, for status 2, in addition to the local state of TextNumber = 5, there are 3 function buttons whose corresponding functions cannot be triggered when pressed, and it is necessary to generate a text prompt explaining why it is not possible. Therefore, 4 groups of text prompts are required. By analogy according to the process, the limit ranges of the text numbers corresponding to the 12 operation states are determined respectively.

[0043] It should be noted that in the embodiments of the present invention, when in any of the above operation states, when a function that cannot be operated is pressed, the text number TextNumber will change to the corresponding text number, and the corresponding text prompt corresponding to the text number will be displayed on the operation interface. The text prompt will prompt how to operate to achieve the function that cannot be achieved in the current state, and the prompt time is maintained at the program - set time. After the timeout, it will change to the prompt text value of the current state. For example: in status 1, when the "start" button is pressed, TextNumber will change from 0 to 1, and the text prompt will display "The reset has not been completed in the initial state, cannot start, please reset first (long - press)". After reaching the set prompt time, TextNumber will change from 1 to 0, and the text prompt will change back to "The reset has not been completed in the initial state, please reset first (long - press)".

[0044] To avoid accidental triggering of the function buttons, in the embodiments of the present invention, when triggering the start, tape guiding, and reset function actions, a delay time for triggering is set, and after the corresponding function action is successfully triggered, based on the trigger signal corresponding to the corresponding function action, the position of the digit flag corresponding to the function action is adjusted; the trigger delay time is, for example, 3S, and a trigger buzzer can also be set synchronously during the process of triggering the function. After the position of the digit flag corresponding to the function action is set to 1, the buzzer stops sounding, so that an intuitive reminder effect can be given to technicians, improving the safety of the system.

[0045] At the same time, in the embodiments of the present invention, the buzzer will only sound when triggering the three functions of start, tape guiding, and reset. Correspondingly, the alarm clearing method also matches it. For example, in the case where the alarm has stopped, press the clear button to clear the alarm. When the machine is stopped and the system alarm has not been cleared, during the "program scan time" when the three functions of start, tape guiding, and reset are successfully triggered, when performing the program scan operation, the stop function of alarm triggering will be blocked, and all alarms in the system will be cleared at the same time. After the next "program scan time", the system will calculate and judge the abnormal signal again. If there is still an abnormality, the stop function of the machine will be triggered. This way of handling alarms will be more user-friendly, and at the same time, the program scan time is very short and does not affect the braking of the alarm.

[0046] Optionally, after the function operation changes from the automatic mode to the manual mode, it sometimes needs to be reset and sometimes does not need to be reset. Therefore, in the program design of the function operation, the embodiments of the present invention add a flag bit of "NotRepeatReset". When "NotRepeatReset" is set to 0 in the program, after the function operation changes from the automatic mode to the manual mode, it will automatically return to "State 1", and at this time, it needs to be reset again. When "NotRepeatReset" is set to 1 in the program, after the function operation changes from the automatic mode to the manual mode, it will return to "State 5", and at this time, it does not need to be reset again. The same operation program can be applied to different machine function requirements. The flag bit of "NotRepeatReset" is used to change the operation process.

[0047] Optionally, in terms of dangerous operation protection, in addition to the above-mentioned need to long-press the function button to trigger successfully when triggering the three functions of start, tape guiding, and reset, there will also be a buzzer prompt during the triggering process. By adding a function of operation authority, in addition to automatically popping up "authority input" when triggering through the normal operation interface, there are also conditional restrictions on the operation authority of the external entity buttons for triggering these three functions on the machine.

[0048] For example, the implementation method of the physical button "operation permission": Through the bus (network) IP, the CPU obtains the permission number of the operation screen. When the obtained permission number is not 0, the physical button can trigger the corresponding function of the program. Otherwise, during the "program scan time" triggered by the physical button, an alarm prompt will be generated.

[0049] After successful startup, first, the system detects whether there are interference conditions for running and executing. After the machine tool meets the conditions for running and is ready to start, in the set start-stop t time of this embodiment of the present invention, the tape running speed is controlled to reach the initial gear. After the overall line tension is established, it starts to accelerate according to the target speed until the target speed is reached.

[0050] The initial gear is, for example, the first slow gear (generally, this speed is used for building tension and guiding the tape). The start-stop t time is triggered in the form of a pulse, and the original basic speed is compared with the target speed. When the basic speed < target speed, a pulse of one t time adds a variable speed to the original basic speed until the basic speed >= target speed, then "the speed base" = target speed. When the basic speed > target speed, a pulse of one start-stop t time subtracts a variable speed from the original basic speed until the basic speed <= target speed, then the basic speed = target speed. After the basic speed reaches the initial gear, it finally starts to accelerate or decelerate according to the target speed until the target speed is reached.

[0051] When the stop trigger is activated, a pulse of one t time subtracts a variable speed from the original basic speed until the basic speed <= 0, then the basic speed = 0.

[0052] The basic speed is the target speed that the servo motor needs to run, which is the linear speed.

[0053] In the automatic state, when selecting tape guiding operation and switching to start, click the start trigger button, and the start function will be successfully triggered. At this time, there is no delay in starting, and the basic speed will then start from the current value and be adjusted according to the above principles.

[0054] In order for the servo drive to quickly respond to the change in the speed value of the basic speed, when the tape running condition is met and the tape running starts successfully, the signal that triggers the "operation activation" of the servo will become 1 in one "program scan time" and become 0 in the next "program scan time", and then alternate during the running process.

[0055] Optionally, according to different material properties, this embodiment of the present invention can select appropriate optimization of the start-stop t time and speed variable parameters, so that when the speed needs to be changed, it can be changed arbitrarily within the specified speed range without considering the problem of tape breakage, improving the applicability.

[0056] Optionally, similarly, corresponding text prompts can also be set during the start-stop process. The number of texts is also an INT-type data. For specific reference, please refer to the foregoing embodiments, and the present invention will not elaborate herein. According to the steps of data collection, logical operation processing, and machine operation, the machine status can be displayed in real time.

[0057] The start-stop method of the double-steel-belt thinning composite machine platform described in the embodiments of the present invention has the following advantages compared with the prior art: 1. When starting up, the machine can first reset and self-check for alarms, and then start running after the reset is successful, improving the stability of the machine platform; 2. It integrates multiple different operation functions, and the function operations or data and text displays are carried out in the form of configuring function buttons on the display interface, improving the convenience of use; 3. Due to the special nature of the material for double-steel-belt film formation, it is necessary to keep the machine running without stopping after tape guiding. The present invention can start running directly without stopping by first guiding the tape slowly and then accelerating after the tension is established, with better working efficiency; 4. By defining and setting the alarm function, reminders are given when the corresponding function operations are incorrect; 5. Define the status parameters and text prompts corresponding to the corresponding function operations, which can visually remind technicians when they perform corresponding function actions. Even technicians without training can quickly get started, reducing the operation difficulty, improving the applicability, reducing the labor cost, and improving the operation efficiency of the machine platform; 6. According to the different materials, different gears are set to adapt to the material acceleration or deceleration, and the speed is increased or decreased according to the set gear after starting or stopping, reducing the tape breakage problem of such machine platforms.
