All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a crane control method based on an electroplating line, which is suitable for a scenario where an upper computer on the electroplating line controls a crane to operate.
As shown in fig. 1, the technical solution provided by this embodiment may include the following contents:
s110, acquiring a contact request sent by the process tank through the programmable logic controller, wherein the contact request carries process tank information of the process tank, and the process tank information comprises a position coordinate corresponding to the process tank and a process flow number.
For the copper plating process shown in fig. 2, the corresponding process flow sequentially comprises 13 process flows of feeding, cleaning, hot water washing, acid washing, copper plating, high-level water washing, blanking, stripping, high-level spray washing, high-level water washing, drying, feeding returning and the like, the 13 process flows are numbered as 1-13, each process flow is completed on a corresponding process groove, wherein the feeding operation with the number of 1 needs manual execution by a user, and the subsequent process flows with the numbers of 2-12 can all be automatically sent to an upper computer by an editable logic controller to meet a request to a crane to complete the corresponding process flow.
The realization principle that the editable logic controller automatically sends the engagement request to the upper computer is as follows: the process flow corresponding to the copper plating process is fixed, the fixed process flow is stored in the programmable logic controller, when a user finishes the feeding operation manually and inputs a feeding confirmation instruction through a key, the programmable logic controller can confirm the execution time point corresponding to a single process flow according to the fixed process flow, and the programmable logic controller replaces the corresponding process slot to send a corresponding contact request to an upper computer at the corresponding execution time point.
In one embodiment, the programmable logic controller takes the time when a user inputs a feeding confirmation instruction through a key as a time starting point, replaces a cleaning groove in a request state at the time A1 according to a fixed process flow of a copper plating process, and sends a contact request to an upper computer, wherein the contact request carries process groove information of the cleaning groove, and the process groove information comprises but is not limited to position coordinates corresponding to the cleaning groove and a process flow number 2; replacing the hot water washing tank in a request state at the moment A2, and sending a contact request to an upper computer, wherein the contact request carries process tank information of the hot water washing tank, and the process tank information comprises but is not limited to a position coordinate and a process flow number 3 corresponding to the hot water washing tank; … …, respectively; the programmable logic controller replaces the process slot in the request state at the corresponding execution time point in sequence, and sends corresponding engagement requests to the upper computer. The upper computer receives the engagement request, and can obtain the process groove information of the corresponding process groove from the engagement request, namely the position coordinate and the process flow number corresponding to the process groove. The programmable logic controller stores information such as position coordinates and process flow numbers corresponding to each process groove; the working states of the process tank when the process tank is not in fault comprise an idle state, a processing state, a request state, a waiting state and the like, the programmable logic controller can judge the working state corresponding to each process tank according to a fixed process flow, and when the process tank enters the request state, the programmable logic controller replaces the process tank to send a corresponding contact request to an upper computer.
And S120, responding to the engagement request, and acquiring all crane information on the electroplating production line from the programmable logic controller, wherein the crane information comprises a number, a working state, a working mode and a position coordinate corresponding to the crane.
Optionally, the acquiring a request for meeting, sent by the process slot through the programmable logic controller in S110, may include: and simultaneously acquiring the engagement requests sent by a plurality of process tanks through the programmable logic controller.
Accordingly, the responding to the request for engagement in S120 may include: and responding the meeting request carrying the maximum process flow number according to the process flow numbers carried by the multiple meeting requests.
In one embodiment, a plurality of copper plating process flows can be simultaneously executed on an electroplating production line, and the programmable logic controller can replace a plurality of process tanks with different numbers and in a request state and send a plurality of contact requests to an upper computer. For example, the programmable logic controller replaces a cleaning tank with the process flow number of 2 to send a contact request to an upper computer, and also replaces a hot water washing tank with the process flow number of 3 to send a contact request to the upper computer; correspondingly, the upper computer receives two engagement requests sent by the cleaning tank and the hot water washing tank through the programmable logic controller simultaneously, process tank information carried by the two engagement requests is obtained respectively, and the upper computer preferentially responds to the engagement request carrying the maximum process flow number (namely, the process flow number 3) based on a preset process tank request priority rule, namely preferentially responds to the engagement request corresponding to the hot water washing tank.
Optionally, the obtaining a request for engagement sent by the process slot through the programmable logic controller may further include: and simultaneously acquiring the engagement requests sent by the process tanks corresponding to the same process flow number in the main process and the plurality of auxiliary processes through the programmable logic controller.
Accordingly, the responding to the request for engagement in S120 may include: counting the number of times of requests for sending the contact requests accumulated by the process tank through the programmable logic controller; responding the meeting request sent by the process slot with the least number of corresponding requests through the programmable logic controller.
In another embodiment, a plurality of copper plating process flows can be simultaneously executed on the electroplating production line, one copper plating process flow is used as a main flow, a copper plating process flow other than the main flow is used as a sub-flow, correspondingly, a plurality of process tanks corresponding to the same process flow are provided, and the plurality of process tanks are numbered identically, for example, 10 cleaning tanks are provided on the electroplating production line, the process flow numbers are all 2, 10 hot water washing tanks are provided, and the process flow numbers are all 3. At the same time, when a plurality of process tanks with the same process flow number in the main process and a plurality of auxiliary processes are all in a request state, the programmable logic controller replaces the plurality of process tanks with the same process flow number and simultaneously sends a plurality of engagement requests to the upper computer. For example, the programmable logic controller replaces 5 cleaning tanks in a request state and simultaneously sends 5 engagement requests to an upper computer; correspondingly, the upper computer receives 5 meeting requests sent by 5 cleaning tanks in a request state through the programmable logic controller at the same time, counts the number of times of the requests sent by the 5 cleaning tanks through the programmable logic controller respectively, compares the obtained 5 request times, and responds the meeting requests sent by the corresponding process tank with the minimum number of times of the requests through the programmable logic controller preferentially based on the preset process tank request priority rule.
In summary, in this embodiment, the main contents of the upper computer following the preset request priority rule are as follows: 1. when the upper computer simultaneously acquires a plurality of process slots with different process flow numbers and the access requests sent by the programmable logic controller, the process slots with larger process flow numbers have higher corresponding priority of the access requests; 2. when the upper computer simultaneously acquires a plurality of process slots corresponding to the same process flow number and the access requests sent by the programmable logic controller, the priority of the access requests corresponding to the process slots with the smaller request times of the access requests is accumulated to be higher by the programmable logic controller. Aiming at the 1 st request priority rule, the upper computer preferentially processes the process flow with larger process flow number, so that the dead control flow of the crane can be better avoided, and the process flow before the execution is meaningful only when the subsequent process flow is executed; aiming at the 2 nd request priority rule, the upper computer preferentially processes the process flows corresponding to the process slots with less accumulated request times, so that the working strength of the process slots can be more reasonably distributed, and the service life of a certain process slot is prevented from being shortened due to the fact that the request times of sending the meeting request are too much.
And S130, determining a target crane which is closest to the process groove from the cranes in the idle state and the automatic mode according to the crane information and the position coordinates of the process groove.
Illustratively, the working modes of the crane comprise an automatic mode and a manual mode, and the upper computer can send an instruction to the crane in the automatic mode to control the crane to automatically run; the states of the crane include a working state, an idle state, a waiting state, an evasive state, a fault state and the like. And the upper computer responds to a contact request sent by the process tank through the programmable logic controller, and respectively calculates the distances between all cranes in an idle state and an automatic mode and the process tank based on a preset crane response priority rule, and takes the crane closest to the process tank as a target crane.
Preferably, if the upper computer determines that a plurality of target cranes closest to the process tank are provided, namely, the target cranes are the same in distance and closest to the process tank, the target crane with the smallest number is selected as the final target crane based on a preset crane response priority rule.
In summary, in this embodiment, the main content of the upper computer following the preset crane response priority rule is as follows: in the cranes in the idle state and in the automatic mode, the crane closest to the process slot that issues the engagement request has the highest priority, and further, if there are a plurality of cranes closest to the process slot, the crane with the smallest number has the highest priority.
And S140, sending a response instruction carrying the process tank information to the target crane according to the number of the target crane so as to control the target crane to move to the process tank and execute corresponding process flow operation.
Illustratively, the target crane moves to the position of the process tank according to the process tank information (including the position coordinates and the process flow number corresponding to the process tank) carried by the response instruction, and executes the process flow operation corresponding to the process tank.
In one embodiment, as shown in FIG. 3, the hoist on the electroplating line is communicatively connected to the upper computer via a bus, and the process tank is communicatively connected to the upper computer via a programmable logic controller via a bus. The electroplating production line is provided with a plurality of cranes 5, 6, 7 and the like in an automatic mode, wherein the cranes 5, 7 are in an idle state, and the crane 6 is in a working state; when the process tank 2 sends a contact request to the upper computer through the programmable logic controller, the upper computer sends a response instruction to the crane 5 which is in an idle state and is closest to the process tank 2, and the crane 5 moves to the process tank 2 according to the position coordinates and the process flow corresponding to the process tank 2 and executes corresponding process flow operation.
In conclusion, in the technical scheme of the embodiment, the process tank and the crane interact in a request response mode through the upper computer, a complex operation line does not need to be established for the crane on the electroplating production line in advance, the response of the optimal crane can be obtained in the fastest time when the process tank is engaged with the request every time, and the stability of crane control and the production efficiency of the electroplating production line are improved.
