[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the embodiments of the present invention.

[0042] The existing method for replacing electrode caps mostly uses manual replacement. When multiple welding tongs on the welding island are in use, any welding tong with a cap replacement request needs to be replaced immediately. The cap replacement time is proportional to the number of welding tongs, that is, the more welding tongs there are in the welding island, the greater the time loss for replacement, which has an adverse impact on the welding work efficiency of the welding island. The following embodiments of the present invention will specifically elaborate on how to improve the welding work efficiency of the welding island.

[0043] Please refer to Figure 1 , Figure 1 It is a flowchart of a maintenance method for a welding island provided by an embodiment of the present invention, and the method includes:

[0044] S11. Encoding multiple welding tongs of the welding island and setting the production tempo of the welding island.

[0045] Specifically, there are various ways to encode multiple welding tongs, as long as each welding tong can have a unique welding tong encoding information. For example, when 4 welding tongs are installed on the welding island, each welding tong can be sequentially numbered with Arabic numerals 1, 2, 3, and 4 to make each welding tong have unique welding tong encoding information; of course, other encoding methods can also be used for encoding. The production tempo of the welding island can be set based on the welding product duration or according to the upstream and downstream processes of the welding island, so that the welding island can be smoothly connected with other processes. After encoding multiple welding tongs and setting the production tempo, proceed to step S12.

[0046] S12. According to the production tempo, obtain the production time of the welding island and the intermittent time between adjacent production times, where the production time is the single continuous production duration of the welding island.

[0047] Specifically, the production tempo characterizes the working time sequence of the welding island. Taking the welding of a white body in white as an example, before welding, the white body in white needs to be clamped to the welding island first, and then multiple welding tongs weld the preset welding points on the white body in white. After welding, the manipulator moves the white body in white to the next process, and the welding island welds the next white body in white. To ensure the smooth progress of the white body in white production line, after welding multiple white bodies in white, it is necessary to pause for a period of time before continuing welding to make the connection between other production processes and the welding process of the production line smooth. The production duration of the welding island for continuously welding the white body in white once is the production time, and the intermittent time is the duration of pausing welding between adjacent production times. It can be understood that both the production time and the intermittent time can be fixed durations, and the welding island cycles periodically based on the production time and the intermittent time; of course, the production time and the intermittent time can also be free durations and be dynamically adjusted according to the actual production situation of the production line. After obtaining the production time and the intermittent time, proceed to step S13.

[0048] S13. According to the usage limit of the electrode caps on the welding tongs and the number of welds in each production time, obtain the target intermittent time for replacing the electrode caps.

[0049] Specifically, the electrode cap is a consumable part on the welding tongs. When the number of welding times of the electrode cap reaches the usage limit, it indicates that its service life has ended, and the electrode cap needs to be replaced in a timely manner to ensure that the welding island can continue to weld the workpiece to be welded. Since the production time represents the single continuous production duration of the welding island, based on this, the number of welding times of the electrode cap at each production time can be determined. To reduce the impact of replacing the electrode cap on the welding efficiency, it is necessary to ensure that the electrode cap is replaced during the break time as much as possible. The production time when the number of welding times of the electrode cap reaches the usage limit will cause welding interruption, so the electrode cap needs to be replaced in advance. Therefore, the target break time is the break time immediately before the production time when the usage limit is reached.

[0050] In practical applications, since the number of welding islands is large, if the target break time for replacing the electrode cap of each welding tong is calculated sequentially, it will consume a lot of calculation time. Based on this, in a specific implementation, according to the usage limit of the electrode cap on the welding tong and the number of welding times at each production time, the target break time for replacing the electrode cap is obtained, including:

[0051] Perform parallel cumulative summation on the number of welding times of each welding tong at each production time to obtain the cumulative number of welding times of each welding tong at each production time; determine whether the cumulative number of welding times is greater than the usage limit; if so, determine the break time immediately before the production time corresponding to the target cumulative number as the target break time of the welding tong, where the target cumulative number is the cumulative number of welding times with the smallest difference from the usage limit among all cumulative numbers of welding times.

[0052] Specifically, taking the welding tong as a unit, a calculation model is established for each welding tong. Based on multiple calculation models, the number of welding times of each welding tong at each production time is calculated in parallel, and the cumulative number of welding times of each welding tong at each production time is obtained through cumulative summation. The cumulative number of welding times increases sequentially with the production time sequence. When determining whether the cumulative number of welding times is greater than the usage limit, it can be judged sequentially according to the order of the cumulative number of welding times from small to large. When the target cumulative number is greater than the usage limit, it indicates that the electrode cap reaches its service life during this production time. To avoid affecting the welding efficiency of the welding island, the electrode cap needs to be replaced in advance, and the break time immediately before the production time corresponding to the target cumulative number is determined as the target break time of the welding tong. When the cumulative number of welding times is not greater than the usage limit, it indicates that the electrode cap does not reach its service life during this production time, and the electrode cap does not need to be replaced. Those skilled in the art can understand that calculating the target break time of each welding tong through multi-threaded parallel computing can improve the calculation speed and is conducive to reducing the response time for outputting the target break time. After obtaining the target break time for replacing the electrode cap, proceed to step S14.

[0053] S14. Output the target intermittent time and the welding torch coding information corresponding to replacing the electrode cap to maintain the welding island.

[0054] Specifically, the welding torch coding information characterizes the identity information of the welding torch that needs to replace the electrode cap. After outputting the target intermittent time and the corresponding welding torch coding information, it is possible to know the specific time and the corresponding welding torch for replacing the electrode cap. When maintaining the welding island, the electrode cap can be replaced accurately and in a timely manner to ensure the welding efficiency of the welding island. It can be understood that the output target intermittent time and the corresponding welding torch coding information can be output to the electrode cap replacement device for automatic replacement of the electrode cap; or the target intermittent time and the welding torch coding information can be output to the central control screen of the welding island for display to facilitate manual response for replacement. It should be noted that due to the disadvantages of large equipment investment, poor reliability of cap replacement, easy damage to the electrode rod during the cap replacement process, and only supporting a limited number of structural forms of electrode caps and not supporting angled or special-shaped electrode caps for the electrode cap replacement device, it is therefore preferred to replace the electrode cap manually.

[0055] In actual application, based on the above strategy, when an electrode cap of a welding torch in the welding island needs to be replaced, the electrode caps of other welding torches (whose service life has not reached the end) can be replaced in advance at the same time. Although this method saves the replacement time, it may cause waste of electrode caps and artificially increase the production cost. Therefore, it is necessary to balance the welding efficiency of the welding island and the replacement cost of vulnerable parts. Based on this, in a specific implementation manner, after obtaining the target intermittent time for replacing the electrode cap according to the usage limit of the electrode cap on the welding torch and the number of welds per production time, the method further includes:

[0056] Obtain the loss information for replacing the electrode cap; according to the loss information, output the replacement time for replacing the electrode cap and the corresponding welding torch coding information.

[0057] Specifically, the loss information can characterize the loss value generated when replacing the electrode cap in advance. When the loss value characterized by the loss information is too large, for example, the loss value is greater than the set value threshold, then output the normal replacement time of the electrode cap and the corresponding welding torch coding information to replace the electrode cap during downtime. It balances the welding efficiency of the welding island and the replacement cost of the electrode cap, making the prediction of the replacement time of the electrode cap more accurate.

[0058] Of course, to balance the welding efficiency and the replacement cost of the electrode caps, it is also possible to obtain the quantity limit for replacing the electrode caps during the intermittent time; determine whether the replacement quantity of the electrode caps during the target intermittent time is greater than the quantity limit; if so, it means that it is rather cramped to replace all the electrode caps to be replaced during the target intermittent time, then according to the loss value of replacing the electrode caps, output the replacement time of the electrode caps and the corresponding welding torch coding information. The loss value can be characterized by the first value of downtime replacement and the second value of electrode cap loss during early replacement, so as to replace the electrode caps at a lower maintenance cost; if not, it means that all the electrode caps to be replaced can be replaced during the target intermittent time, then output the target intermittent time and the welding torch coding information corresponding to the replaced electrode caps. Through this strategy, the requirement of welding efficiency is preferentially met, and at the same time, the replacement cost of the electrode caps is further balanced.

[0059] To more comprehensively evaluate the loss of replacing the electrode caps, in a specific implementation, the loss information includes a first loss value and a second loss value. According to the loss information, output the replacement time of the electrode caps and the corresponding welding torch coding information, including:

[0060] Obtain the first loss value according to the downtime duration of the welding island and the production cost during downtime, where the downtime duration is the duration of the welding island stopping to replace the electrode caps during the production time; obtain the second loss value according to the value loss of early replacement of the electrode caps during the intermittent time when the usage times limit is not reached; when the first loss value is greater than the second loss value, then output the target intermittent time and the corresponding welding torch coding information; when the first loss value is not greater than the second loss value, then output the downtime replacement time and the corresponding welding torch coding information.

[0061] Specifically, the production cost during downtime is the loss of the production line caused by the welding island stopping during unit time, such as the loss cost per second when the welding island stops. The first loss value is the product of the downtime duration and the production cost during downtime, which characterizes the loss value of normal downtime replacement when the electrode cap reaches its service life; the second loss value characterizes the loss value of consumables generated when the electrode cap is prematurely replaced during the target intermittent time and does not reach its service life. When the first loss value is greater than the second loss value, it means that the loss caused by early replacement of the electrode cap is smaller, then output the target intermittent time and the corresponding welding torch coding information, and replace the electrode cap in advance during the target intermittent time. When the first loss value is not greater than the second loss value, it means that the loss caused by normal downtime replacement of the electrode cap is smaller, then output the downtime replacement time and the corresponding welding torch coding information. The downtime replacement time characterizes the consumption duration of stopping to replace the electrode cap during the production time. Through the above strategy, the welding efficiency and the replacement cost of the electrode caps can be balanced at a lower cost, and it can meet the optimized centralized replacement of the electrode caps of multiple welding torches in the welding island, thereby improving the replacement efficiency and the utilization rate of the electrode caps.

[0062] In practical applications, the second loss value can be calculated based on the usage duration of the electrode cap during the production time and the time limit corresponding to the service life. However, the usage duration needs to be a variable measured independently for each welding tong, which is likely to cause redundant calculations. Based on this, in a specific implementation manner, the second loss value is obtained according to the value loss caused by replacing the electrode cap in advance during the intermittent time before the usage times limit is reached, including:

[0063] According to the formula The second loss value V is obtained D , where N max is the usage times limit, N now is the number of welding times when replacing the electrode cap, and A is the price of a pair of electrode caps.

[0064] Specifically, the usage times limit N max can be determined through aging tests and the inherent properties of the electrode cap. The number of welding times N now can be determined by real-time monitoring during the use of the welding island. In resistance welding, it is completed by the opposite welding of two electrode caps. Therefore, the price A of a pair of electrode caps can determine the value of the vulnerable parts of a welding tong. Through the above formula, the second loss value V can be accurately calculated D , while reducing redundant calculations.

[0065] In a specific implementation manner, after outputting the target intermittent time and the welding tong coding information corresponding to the replaced electrode cap, the method further includes:

[0066] Receiving the completion instruction for the electrode cap replacement; outputting a clearing instruction according to the completion instruction to clear the number of welding times of the corresponding welding tong.

[0067] Specifically, the completion instruction can be issued by manually triggering the button on the welding island after the cap replacement by the operator. Receiving the completion instruction indicates that the electrode cap has been replaced, then the clearing instruction is output to clear the number of welding times of the welding tong. When continuing welding on the welding island, the number of welding times of the corresponding welding tong is continuously measured to continue reminding the user how to maintain the welding island. It should be noted that the target intermittent time and the corresponding welding tong coding information can be output to a preset APP (Application). The target intermittent time and the welding tong coding information are displayed in real time on the APP. Of course, the APP can also remind the user to prepare for the electrode cap replacement in the form of acoustic and optical alarm information, or output the target intermittent time and the welding tong coding information for maintaining the welding island based on the user's query instruction. The functions of the APP are not specifically limited here.
