[0031] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0032] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] Figure 1 is a flow chart showing a group-level production equipment maintenance management method according to some embodiments of the present disclosure. Figure 1 As shown, the method includes steps S102 to S110.

[0038] In step S102, a maintenance record of the production equipment is established, and the maintenance record includes status information and location information of the production equipment.

[0039] The maintenance record is a list of equipment that indicates which production equipment needs maintenance. The maintenance record includes the status information and location information of the production equipment. Here, the status information may include the status information such as the equipment is in use, the equipment is idle, and the equipment is sealed.

[0040] It should be noted that the "maintenance" disclosed in this disclosure refers to inspection, maintenance, etc.

[0041] In step S104, the maintenance standards are grouped according to the equipment types of the production equipment to obtain a plurality of maintenance standard groups, wherein the equipment types are bound to the maintenance standard groups in a one-to-one correspondence.

[0042] Here, a company-level maintenance standard library is established. Figure 2 is a schematic diagram showing a maintenance standard library for production equipment according to some embodiments of the present disclosure. Figure 2 As shown, the maintenance standards are grouped according to the equipment type. For example, equipment type 1 corresponds to maintenance standard group 1, which includes maintenance standards 1 to i; equipment type m corresponds to maintenance standard group m, which includes maintenance standards i+1 to m, etc., where 1≤i≤m, i and m are positive integers. This allows the binding of similar production equipment to maintenance standard groups. Here, production equipment can be maintained with different maintenance standards, etc. Each maintenance standard contains data such as maintenance target parameters and maintenance frequency.

[0043] In step S106, the equipment maintenance and operation qualifications are grouped according to the equipment type to obtain multiple equipment maintenance and operation qualification groups, wherein the equipment maintenance and operation qualification groups correspond to the equipment types one by one, and each equipment maintenance and operation qualification group includes one or more equipment maintenance and operation qualifications.

[0044] Here, an equipment operation qualification database is established. Figure 3 is a schematic diagram showing the management of a production equipment operation qualification library according to some embodiments of the present disclosure. Figure 3 As shown in the figure, equipment maintenance and operation qualifications are grouped according to equipment type. For example, Figure 3 , it is shown that operator 1 corresponds to operation qualification groups 1 to j, and operator p corresponds to equipment maintenance operation qualification groups j to u, where j, p and u are positive integers. Each equipment maintenance operation qualification group can correspond to multiple devices of the same equipment type. For example, Figure 3 Equipment 1 to q are shown in FIG. 1 , where q is a positive integer. Since the skills of operators are different, the corresponding operating qualifications are different. By establishing a mapping relationship among operators, operating qualifications and production equipment, in actual applications, it is possible to ensure that operators with operating qualifications can maintain the corresponding production equipment, and to ensure the effective implementation of maintenance tasks as much as possible.

[0045] In step S108, an operator information database is established, and the operators are bound to equipment maintenance and operation qualification groups, and each operator corresponds to one or more equipment maintenance and operation qualification groups.

[0046] Here, an operator information database is established. The operator information includes the branch, production line, section, etc. to which the operator belongs. That is, the operator information database is the organizational structure to which a certain operator belongs, including the branch, production line, and section information, and the operator corresponds one-to-one to the above branch, production line, and section information. The operator is bound to the equipment operation qualification database to obtain the operation qualification of a certain type / several types of equipment. Each operator corresponds to one or more equipment maintenance operation qualification groups. For example, Figure 3 As shown, operator 1 corresponds to equipment maintenance operation qualification groups 1 to j, and operator p corresponds to equipment maintenance operation qualification groups j to u.

[0047] In step S110, the maintenance ledger, the maintenance standard group and the equipment maintenance operation qualification group are bound to define the maintenance content and operation qualification requirements of the production equipment.

[0048] Here, by binding the maintenance ledger of production equipment with the maintenance standard group and equipment maintenance operation qualification, the maintenance content and operation qualification requirements required for production equipment can be defined.

[0049] For example, the method of binding the maintenance record of production equipment with the maintenance standard group includes: adding the maintenance standard group established in the previous step to the maintenance record of production equipment to bind the production equipment with the required maintenance standard. In addition, the same type of production equipment can be copied to batch set the maintenance standard group for a batch of similar equipment to improve operation efficiency.

[0050] The method for binding the maintenance ledger of production equipment to the equipment maintenance operation qualification group is similar to the method for binding the maintenance ledger of production equipment to the maintenance standard group. For example, the method for binding the maintenance ledger of production equipment to the equipment maintenance operation qualification group includes: adding the equipment maintenance operation qualification group established in the previous steps to the maintenance ledger of production equipment to achieve the binding of production equipment with the required equipment maintenance operation qualification. In addition, the same type of production equipment can be copied to batch set the equipment maintenance operation qualification groups of a batch of similar equipment to improve operation efficiency.

[0051] In step S112, a maintenance task is generated based on the maintenance content and operation qualification requirements of the production equipment, and the maintenance task is sent to the terminal device of the corresponding operator.

[0052] By sending the generated maintenance tasks to the operator's terminal device, the operator can be notified of the maintenance tasks he needs to perform.

[0053] So far, a group-level production equipment maintenance management method according to some embodiments of the present disclosure is provided. The method includes: establishing a maintenance ledger for production equipment, the maintenance ledger includes status information and location information of the production equipment; grouping the maintenance standards according to the equipment type of the production equipment to obtain multiple maintenance standard groups, wherein the equipment type is bound to the maintenance standard group in a one-to-one correspondence; grouping the equipment maintenance operation qualifications according to the equipment type to obtain multiple equipment maintenance operation qualification groups, wherein the equipment maintenance operation qualification group corresponds to the equipment type in a one-to-one correspondence, and each equipment maintenance operation qualification group includes one or more equipment maintenance operation qualifications; establishing an information base for operators, and binding operators to equipment maintenance operation qualification groups, each operator corresponds to one or more equipment maintenance operation qualification groups; binding the maintenance ledger, maintenance standard group and equipment maintenance operation qualification group to define the maintenance content and operation qualification requirements of the production equipment; and generating maintenance tasks based on the maintenance content and operation qualification requirements of the production equipment, and issuing the maintenance tasks to the corresponding terminal devices of the operators. Therefore, a method for digital comprehensive maintenance management of production equipment for group companies is provided here. This method can unify the maintenance process of the group's production equipment, thereby improving the quality and efficiency of maintenance.

[0054] In some embodiments, the above method may further include: generating an electronic equipment tag for production equipment with a unified group code, wherein the basic maintenance information corresponding to the electronic equipment tag includes: a maintenance ledger, a maintenance standard group, and an equipment maintenance operation qualification group. In this way, the electronic equipment tag is generated with a unified group code, integrating basic maintenance information such as equipment ledger information, maintenance standards, and operation qualifications.

[0055] The above about Figure 1 The method shown and the method for generating equipment electronic tags here are all methods involved in establishing basic maintenance information. In terms of establishing basic maintenance information, the maintenance operators are classified according to their types, and basic information management modules such as the group-level production equipment maintenance standard group and the production equipment operation qualification library are introduced. The equipment electronic tags are generated with the group's unified coding, and the equipment ledger information, maintenance standards, operation qualifications and other information are integrated, which can improve the unification, standardization and digitization level of the group's production equipment maintenance process.

[0056] In some embodiments, maintenance tasks may be divided into different types, such as daily periodic maintenance tasks, preventive maintenance tasks, and professional maintenance tasks.

[0057] Here, in terms of automatic generation of maintenance plans, a group-level equipment comprehensive maintenance business process is designed, which is classified into three categories according to maintenance content and operators, namely daily periodic maintenance tasks, preventive maintenance tasks and professional maintenance tasks.

[0058] 1. Daily periodic maintenance tasks include equipment inspection, cleaning, tightening, lubrication and other daily routine maintenance tasks, which are mainly completed by equipment operators.

[0059] 2. Preventive maintenance tasks are routine equipment preventive maintenance tasks. Preventive maintenance plans are formulated every month and are mainly implemented by equipment maintenance workers.

[0060] 3. Professional maintenance tasks include professional maintenance tasks for high-end equipment such as industrial robots, CNC machine tools, and cranes, which are implemented by the group's professional maintenance team.

[0061] Figure 4 is a flow chart showing a group-level production equipment maintenance management method according to other embodiments of the present disclosure. Figure 4 As shown, the method includes steps S402 to S414.

[0062] In step S402, the equipment maintenance type is determined, that is, the type of maintenance task (hereinafter referred to as maintenance type) is determined.

[0063] In step S404, it is determined whether the maintenance type is daily periodic maintenance. If yes, the process proceeds to step S406; otherwise, the process proceeds to step S408.

[0064] In step S406, daily maintenance is performed. The daily maintenance may be performed by an operator. For example, daily maintenance may include daily inspection, daily maintenance, etc.

[0065] In step S408, it is determined whether the maintenance type is preventive maintenance. If yes, the process proceeds to step S410; otherwise, the process proceeds to step S412.

[0066] In step S410, preventive maintenance is performed. The preventive maintenance may be performed by a maintenance worker. For example, the preventive maintenance may include: conventional equipment maintenance, replacement of wearing parts, etc.

[0067] In step S412, it is determined whether the maintenance type is professional maintenance. If yes, the process proceeds to step S414; otherwise, the process returns to step S402.

[0068] In step S414, professional maintenance is performed. The professional maintenance can be performed by the company's maintenance team. For example, the professional maintenance includes high-end equipment maintenance. For example, the high-end equipment maintenance includes: robot maintenance, machine tool maintenance, driving maintenance, etc.

[0069] So far, a group-level production equipment maintenance management method according to other embodiments of the present disclosure is provided. Through the above production equipment maintenance process, full coverage of production equipment maintenance services can be achieved.

[0070] In some embodiments, the above method may also include: establishing production shift information, the production shift information includes at least one shift; generating a shutdown plan for the next maintenance cycle, wherein the shutdown plan includes: the equipment number, shutdown date and shift information of the production equipment that needs to be shut down; automatically generating a maintenance plan for the next maintenance cycle based on the production shift information and the shutdown plan; and obtaining a team shift calendar and a personal shift calendar based on the maintenance plan for the next maintenance cycle. Through this method, the purpose of automatically generating a maintenance plan is achieved, thereby facilitating maintenance operations for operators. The method establishes a method for automatically generating a maintenance plan for production equipment, and realizes all-round digital management and control of equipment maintenance.

[0071] For example, the above method includes the following steps (1) to (4).

[0072] In step (1), the production shift information is established, including at least one shift. For example, the production shift information includes three shifts: day shift, mid-shift, and night shift, and the working time period of each shift can be defined. For example, the day shift time is 8:00-16:00, the mid-shift time is 16:00-24:00, and the night shift time is 24:00-8:00.

[0073] In step (2), during the last several (e.g., 5) working days of each month, the system maintains the downtime plan for the next month (i.e., the next maintenance cycle), including the downtime equipment number, downtime date, shift, etc. For example, the maintenance downtime plan can be set in batches, such as batch setting that there is no working shift on Sundays of each month.

[0074] In step (3), according to the set production shifts, downtime plans and other information, the system automatically generates a monthly maintenance plan within a predetermined number of (for example, 3) working days.

[0075] In step (4), the team shift calendar and personal shift calendar are displayed according to the shift schedule. Here, the team shift calendar is mainly for the team leader to view, showing the shift schedule of all members in the team within a certain period (month / week / day); the personal shift calendar is mainly for the operator to view, showing the personal shift schedule within a certain period (month / week / day).

[0076] In addition, the final maintenance plan can be modified and determined based on the actual production plan of the branch factory, and batch modification of the maintenance plan is supported.

[0077] In some embodiments, a maintenance plan for the next maintenance cycle is automatically generated based on the production shift information and the downtime plan, including: generating a date matrix based on the production shift information and all dates of the next maintenance cycle, wherein the elements of the date matrix include downtime dates and normal working dates; establishing a shift vector based on the production shift information; and calculating the scheduling data matrix for the next maintenance cycle based on the date matrix and the shift vector as the maintenance plan for the next maintenance cycle. In this way, the purpose of generating a maintenance plan for the next maintenance cycle based on the production shift information and the downtime plan is achieved. In terms of automatic generation of maintenance plans, the method establishes a method for automatically generating maintenance plans for production equipment, and realizes all-round digital management and control of equipment maintenance.

[0078] The following example describes the specific process of generating a maintenance plan for the next maintenance cycle.

[0079] Take the example of automatically generating the next month's maintenance plan at the end of this month. First, set the planned downtime date for next month in the system. For example, if the system takes a rest every Sunday next month, set the 7th, 14th, 21st, and 28th as downtime days, and the normal working shifts are day shift, mid-shift, and night shift. Create a date matrix:

[0080] , (1)

[0081] Where: shutdown date d7=0, d 14 =0,d 21 =0,d 28 = 0, other normal working days d i =1.

[0082] Then, build the shift vector:

[0083] , (2)

[0084] Among them: b1 is the day shift, b2 is the mid-day shift, b3 is the night shift, no shift is "0", and there is a shift is 1. Then, the shift data matrix P is:

[0085] , (3)

[0086] Right now,

[0087] , (4)

[0088] Where: P i is the shift scheduling vector for the i-th day of the next month, P i1 For the day shift, P i2 For the middle class, P i3The return value is 0 for no shift, and 1 for shift. The above scheduling algorithm is easy to operate. You only need to set the shutdown date and the working shift to automatically schedule the shift. Here, the scheduling data matrix P can be used as the maintenance plan for the next maintenance cycle.

[0089] In terms of the automatic generation of the above-mentioned maintenance plan, the embodiments of the present disclosure can establish an automatic generation of production equipment maintenance plans and a maintenance execution early warning algorithm to achieve all-round digital management and control of equipment maintenance.

[0090] In some embodiments, the above method may also include: according to the set pre-shift maintenance reminder time threshold, sending a first reminder message to the terminal device of the corresponding operator to remind the operator of the task before the maintenance task of each shift is executed; according to the set mid-shift maintenance reminder time threshold, sending a second reminder message to the terminal device of the corresponding operator to remind the operator of the task during the execution of the maintenance task of each shift; and according to the set post-shift maintenance reminder time threshold, sending a third reminder message to the terminal device of the corresponding operator to remind the operator of the task after the maintenance task of each shift is completed. In this way, it is realized that the operator is reminded of the task before, during and after maintenance, so as to prevent the omission of maintenance operations as much as possible.

[0091] For example, maintenance tasks can be divided into pre-shift maintenance, mid-shift maintenance, and post-shift maintenance according to different execution time periods.

[0092] During the maintenance execution process of the day, task reminders will be given in advance in the day shift, mid shift, and night shift according to the set task reminder threshold.

[0093] Set the pre-shift maintenance reminder time threshold t1. The pre-shift maintenance task is to maintain the production equipment before the production task is carried out. Task reminders can be used to improve the maintenance personnel's ability to carry out a pre-shift maintenance task that has not been carried out, and try to ensure that the maintenance task is carried out according to the time period requirements. During the actual execution process, the maintenance personnel can quickly enter the maintenance execution interface by clicking the task reminder on the terminal side, improving the convenience and efficiency of operation.

[0094] , (5)

[0095] Where: T bq is the reminder time before the day shift, T zq It is the reminder time before the middle shift, T wq To remind you of the time before the night shift, in fact, T wq As a reminder for the next day.

[0096] Set the maintenance reminder time threshold t2. Maintenance during a shift is the task of maintaining production equipment during the production process. Task reminders are reminders sent to operators of unperformed maintenance to ensure that maintenance tasks are performed on time.

[0097] , (6)

[0098] Where: T bz is the waking time during the day shift, T zz Reminder time for the middle class, T wz To remind the night shift, in fact, T wz The reminder time for the next day.

[0099] Set the time threshold t3 for after-shift maintenance reminder. After-shift maintenance is the task of maintaining production equipment after the production task is completed. The reminder content is similar or the same as before and during the shift.

[0100] , (7)

[0101] Where: T bh The reminder time after the day shift, T zh It is the reminder time after the middle shift, T wh To remind you of the time after the night shift, in fact, T wh As a reminder for the next day.

[0102] The operator's terminal device (for example, mobile terminal) can receive maintenance task reminders and click the reminder to directly enter the maintenance execution page.

[0103] Maintenance is performed on the mobile terminal, and maintenance standards are implemented according to the classification of before, during and after the shift. Key maintenance steps are photographed and uploaded to the system. Maintenance work needs to be performed at the production site. Operators follow the mobile terminal maintenance standards one by one. The operation and execution efficiency on the mobile terminal is higher. Key processes only support photo uploading (not supporting the uploading of existing photos), which can ensure that maintenance tasks are performed as required and the authenticity of maintenance is ensured.

[0104] Furthermore, the team leader analyzes the unexecuted results of the previous day, sets the status of non-maintenance, extended warranty, etc., and explains the reasons.

[0105] In terms of maintenance task execution, the branch equipment personnel make batch adjustments to the maintenance plan based on the actual production plan. For the current maintenance plan, thresholds are set to provide task reminders in advance. Maintenance executors perform maintenance on mobile devices. The key maintenance process only supports taking photos to ensure the authenticity of the maintenance.

[0106] In some embodiments, the above method may further include: automatically generating equipment maintenance record sheets of different levels according to the maintenance execution status, wherein the equipment maintenance record sheets include the timely completion rate of maintenance at the corresponding level; wherein the timely completion rate of maintenance L w for

[0107] , (8)

[0108] in, is the total number of maintenance tasks completed on time on day j, is the total number of maintenance tasks that need to be completed on the jth day, T is the total number of days in a maintenance cycle, where 1≤j≤T, j and T are positive integers. By generating equipment maintenance record sheets at different levels, the automation level of generating equipment maintenance evaluation and control can be improved.

[0109] Here, in terms of maintenance performance application, according to the maintenance execution status, equipment maintenance record sheets at different levels such as work teams, work sections, production lines, branches, and enterprises are automatically generated. For different levels or dimensions, the maintenance timely completion rate is calculated using the above calculation formula (8).

[0110] The timely completion rate of maintenance of all maintenance personnel (i.e. operators) in the department can be ranked, and the timely completion of maintenance personnel can be improved through data management and control.

[0111] In addition, it can also be connected with the automated office system to issue weekly / monthly notifications on the ranking indicators of timely completion rate of maintenance.

[0112] In terms of the above-mentioned maintenance evaluation, equipment maintenance statistical reports of different dimensions such as factories, branches, production lines, and work sections are automatically generated and integrated with the office automation system, and automatically sent to relevant management and control departments to improve the automation level of generating equipment maintenance evaluation and control, and realize maintenance status tracking and assessment.

[0113] The embodiments of the present disclosure have designed a comprehensive maintenance plan at the group level. Daily periodic maintenance and predictive maintenance are performed by equipment operators and maintenance personnel. The professional maintenance objects are industrial robots, CNC machine tools, cranes and other equipment with strong maintenance expertise. In order to achieve lean management and control of high-end maintenance personnel and ensure the stability and accuracy of equipment processing, a group-level professional maintenance team and production equipment spare parts library are designed. The maintenance team is divided according to the equipment maintenance type. The number of maintenance personnel required for each maintenance type is:
